| Product | Weight | Tip Over Leak | Cold Retention | Hot Retention | Tip Stability | Drop Test | Lid Open Force | Capacity Test | Corrosion |
|---|---|---|---|---|---|---|---|---|---|
| 1Corkcicle$45 | 635 g | leaked just about the same amount as the Milwaukee when tipped over on its side; leaks pretty badly around the straw gasket when facing upside down | 42.4 F, best of all tumblers tested, moved into the lead over the Stanley | 126 F after 4 hours in the freezer, by far the best of all tumblers tested | 14.6 degrees, struggled laying down | metal straw hit the concrete floor and became bent on impact; small amount of water loss, lid itself not damaged | no force figure given in the narration; the sentence describing this test cuts off ('Let's get the Corkcicle since it remains open with the straw'), likely a caption gap | overflowing before the lid can be fully installed at 30 oz | small amount of corrosion on the top of the tumbler |
| 2Stanley Quencher H2.0 Tumbler$35 | 523 g | leaked a little bit more than the Tervis Cat when tipped over; performed about the same as the Tervis Cat facing upside down | 42.8 F, close second place behind the Corkcicle | 120.2 F, second best behind the Corkcicle, tall/narrow design credited | 15.6 degrees, looked unstable but performed better than some other brands | lid cover flew off on impact and lost a few oz of water, but the lid attachment snapped back into position with no damage | 678 g, pretty easy to rotate | holds the advertised 30 oz with room left for the lid | a little more rust than some of the less expensive tumblers, called an area for improvement |
| 3Buc-ee's$26, same price as the CamelBak | 423 g | leaks pretty badly, just like the CamelBak, both when tipped over and when facing upside down | 43.9 F, coolest yet at that point in the test order | 111.9 F, a lot better than average | 16.8 degrees, quite a bit better than average | lid cover flew off and the sliding cover detached on impact, but was found and snapped back into position without damage | 620 g, raised grip area in a good location, easy to grip and work with | barely held 30 oz with not enough space left for the lid | about the same as the CamelBak, just a small amount of rust |
| 4Chilamics$10 | 304 g, lightest tumbler tested | small amount of water splashed out when tipped over; did not leak when gently placed upside down | 48.7 F, worst cold retention of all tumblers tested | 107.6 F, better than the uninsulated cup but near the low end | 18.1 degrees, performed well | lid came off on impact, spilling close to 30 oz of water, and the lid broke into two pieces | 800 g, about 2 lb of force | holds 30 oz but there is not enough space inside for the lid | experienced quite a bit of corrosion, among the worst tested |
| 5Ozark Trail$19 | 458 g | small amount of water seeping out of the lid when tipped over; held all the water in when placed upside down | 45.1 F, about 3.5 degrees cooler (better) than the Chilamics | 106.7 F, trailed the Chilamics by almost 1 degree | 14.7 degrees | lid came off on impact making a mess, but the lid itself held up with no visible damage | 644 g, easier to open than the Chilamics | seems to hold about the same amount of water as the Chilamics; lid fit not explicitly confirmed | small amount of rust, not nearly as bad as the Chilamics |
| 6Contigo$21 | not tested | not designed to prevent tip-over leaks; leaks quite a bit of water when facing upside down | 45.9 F | 116.1 F, about 8.5 degrees hotter (better) than the Chilamics, credited to its tall/narrow profile and lid design | 15.7 degrees, better than the Ozark Trail despite being tall and narrow | lid took a big impact but stayed on the tumbler; only a few oz of water leaked and no damage to the lid | 340 g, moves without much force, though the push/pull point location makes it a little challenging | rated for 32 oz; held 30 oz with room to spare for the lid | about the same amount of oxidation as the Ozark Trail |
| 7Arctic Tumblers$23 | 410 g | first tumbler in the lineup with zero leakage; held all the water when tipped over and when upside down | 45.7 F, moved into second place behind the Ozark Trail | 104.9 F, struggled, about 2 degrees cooler than the Ozark Trail | 16.7 degrees, less likely to tip than most of the previously tested tumblers | lid stayed mostly in position, losing only a few oz of water, but part of the lid cover broke and the lid became very difficult to open afterward | 380 g, easy access and minimal effort | holds very close to 30 oz | by far the best result seen at that point, no corrosion at all |
| 8Beast$23, same price as Arctic Tumblers | 429 g | held in all the water when tipped over and when placed upside down | 44.8 F, moved into the lead at that point in testing | 104 F; transcript says this is 'about a degree warmer than the Arctic Tumblers,' but the Arctic Tumblers figure given is 104.9 F, so 104 F is actually colder, not warmer; kept verbatim and flagged as an internal inconsistency rather than corrected | 17.1 degrees, moved into second place behind the Chilamics | lid stayed on after impact, but part of the lid cover broke | 1,176 g, about three times the force needed for the Arctic Tumblers | first 30 oz tumbler in the video that actually holds 30 oz with enough room left for the lid | about the same amount of corrosion as the Ozark Trail and Contigo |
| 9CamelBak$26 | just under 400 g | struggled badly tipping over on its side and leaked pretty badly facing down | 44.6 F, moved into the lead at that point in testing | 115 F, performed very well, credited to its tall/narrow profile like the Contigo; transcript then says the Tervis Cat 'struggled...just like the Contigo and CamelBak,' which is inconsistent with CamelBak's own strong 115 F result here; kept verbatim and flagged rather than resolved | 10 degrees, flopped over, the worst stability result in the video; narrow rounded bottom design called out as poor | lost its lid cover on impact, made a mess, but the lid itself survived without damage | 2,228 g, the most force needed of any tumbler tested, described as surprisingly stiff | holds 30 oz and almost has enough room for the lid | performed better than the Beast, but not as well as the Arctic Tumblers |
| 10Norday$29 | 395 g | held everything in when tipped over and when facing upside down | 46.6 F, struggled to keep the water cool | 104.9 F, about the same as the Arctic Tumblers | no specific degree figure stated in the narration; described as looking stable, but rubber padding on the bottom hurt its actual performance | lid came off, and though not visibly damaged it developed a pretty bad crack so the slider no longer opens fully | 1,468 g, does not slide easily; raised grip area harder to work with than the Buc-ee's | almost ran out of space for 30 oz | a lot more rusting than most of the other brands |
| 11Tervis Cat$30 | 439 g | leaked a small amount when tipped over ('marks its territory just a little') and leaked more when facing upside down | 46.2 F, barely edged out the Norday, about 1.5 degrees warmer than average | 103.8 F, described as struggling in this test | 17.8 degrees, stayed on its feet better than most of the competition | took a big bounce on impact and the lid came off, but both lid and tumbler survived without damage | 468 g, very easy to work with, minimal force | very close to overflowing with 30 oz | performed a lot better than most of the other brands |
| 12Yeti MagSlider$38 | 488 g | performed a little better than the Stanley both tipped over and facing upside down | 44.6 F, a little better than average but not as good as the Stanley | 108.5 F, a little better than average but not as good as the Stanley | 17.7 degrees, extremely well, third place behind the Tervis Cat | lid stayed on impact, but the magnetic slider detached; it went back into position without damage | 402 g, very smooth and easy with the magnetic slider | holds 30 oz without the lid, but not enough space for the lid | extremely well, no corrosion at all |
| 13BruMate$40 | 636 g | did not leak a drop tipped over or upside down with the straw position closed; with the straw open, a small amount of leakage tipped over and a little more upside down | 43.5 F, almost as well as the Stanley | 108.3 F, better than average despite not being marketed for hot liquids | 12.3 degrees, next to last place, very prone to tipping over due to a narrow bottom | screw-on lid stayed in place; only a very small amount of water escaped and no damage to the lid | 556 g, part of the lid cover has to rotate to access the straw | holds 30 oz but overflows before the lid can be installed | extremely well, no rust at all |
| 14Milwaukee Packout$40, same price as the BruMate | 534 g | leaked a small amount tipped over; a slow drip facing upside down | 44.4 F, better than average, fourth place behind the Buc-ee's | 112.8 F, a lot better than average | 14.8 degrees, struggled, described as definitely tip-over prone | rotating lid cover flew off on impact but snapped back into position with no damage | 636 g, well designed and pretty easy to access, though a little more force than some other brands | holds 30 oz but the lid does not fit | better than average overall but flagged as an area that could use improvement |
| 15Uninsulated cup$2 | 58 g | performed as well as many of the insulated tumblers when tipped over, but leaked pretty badly facing upside down | not applicable, this baseline was used only in the hot-retention freezer test | mostly frozen after 4 hours in the freezer; specific numeric temperature not stated, described only as 'mostly frozen' | 18.4 degrees, outperformed every insulated tumbler tested, finishing first place | not mentioned in the drop test section | not applicable, no lid | not mentioned in the capacity test section | not mentioned in the corrosion test section |
How it was tested
- tip-over spill/leak test, tipped on its side and placed fully upside down
- cold beverage temperature retention after about 6 hours at roughly 75 F room temperature
- hot beverage temperature retention after 4 hours in a -40 F freezer
- tip angle stability test, degrees of tilt required to reach the tipping point
- 30 inch drop/impact durability test onto a concrete floor
- lid opening force, measured in grams
- 30 oz capacity test, whether the tumbler holds 30 oz with the lid still fitting
- corrosion resistance test using hydrogen peroxide, vinegar, and salt
Data notes and caveats
No single overall winner is declared. The reviewer converts raw scores to letter grades and names three separate favorites in the closing summary: Buc-ee's (best hot and cold beverage grades, stable, average corrosion resistance, but spills if tipped), Stanley (very strong temperature retention, top heavy), and Corkcicle (numerically the best performer in both temperature tests, most expensive, described specifically for cold beverages). Because no single verdict sentence names one overall winner, winner/runnerUp/verdictQuote are left null per spec rather than inferring one from Corkcicle's numeric lead. Two brand-name mangles were resolved by matching the fixed testing order against the description's Products Tested list: 'Chillout Mix'/'Chillamic'/'Chilamix' to Chilamics, and 'Thermos Cap' (corrosion section only) to Tervis Cat. Two internal transcript contradictions were preserved verbatim rather than silently corrected: the Beast's 104 F hot-retention reading is called 'about a degree warmer than the Arctic Tumblers' despite Arctic Tumblers scoring higher at 104.9 F, and the Tervis Cat's 103.8 F 'struggled' result is described as being 'just like the Contigo and CamelBak' even though those two scored well (116.1 F and 115 F) in the same test. Contigo's weight is missing from the transcript entirely ('the heaviest yet g.' with no number spoken), kept null rather than guessed. Chapters were null in the video metadata.
