Curt’s 20 oz Yukon Tumbler account describes a broken slider on the first lid and a replacement that remained tight but worked. That is a reason to inspect a resistant lid, not a reason to force it or assume all examples fail.
Check the mechanism while the cup is empty
- Confirm that the lid belongs to the exact tumbler and is seated as its instructions require. Similar capacity or appearance does not prove compatibility.
- Look for visible debris, damage or misalignment without prying apart the mechanism.
- Use only the cleaning or disassembly method supplied for that exact lid. The captured listing does not provide one.
- If resistance remains abnormal, stop and contact the seller or manufacturer with the model and photographs of the problem.
A working slider does not make a leakproof bottle
The 20 and 30 oz listings describe BPA-free UV-tinted slider lids, but no verified leakproof claim was captured. A cup that closes over the drinking opening may still need upright handling. Do not put a filled tumbler in a bag on the strength of the word “lid.”
| What you observe | Next useful step |
|---|---|
| Tight from new | Keep it empty, check the supplied instructions and request support if abnormal resistance remains |
| Visible broken component | Stop using the damaged lid and request an appropriate replacement |
| Replacement fits differently | Confirm the exact compatible lid revision before use |
| Unclear cleaning instructions | Ask for body and lid care separately; do not borrow the Pint’s dishwasher claim |
The 20 oz Tumbler review preserves the original complaint alongside favorable drink-use reports. The 20 versus 30 oz comparison explains why the smaller sample for the larger cup cannot establish a more reliable lid.
