DRINK IT YOUR WAY
Hate it when your icy-cold drink or steaming hot cuppa turns to room temperature mediocrity? The double walled, vacuum insulated SIPWORKS Coffee Tumbler keeps your beverages chilly for up to 9 hours or scorching for over 3 hours – all while its exterior stays cool and condensation-free!
Made with premium 304, 18/8 food grade stainless steel with rust resistant, anti-slip, fade-proof exquisite powder coated finish, so you can take your SIPWORKS Coffee Tumbler to the classiest of gatherings or raunchiest of parties and it’ll come out unscathed and looking fabulous – indestructibility never looked so good.
I’ve used this 3 times. I haven’t dropped it, but can hear something rattling in between the layers every time I move it/drink out of it.
I like the cup but the blue other cup I had I think was better. The other one hold the heat or cold better. I still like it. Wouldn't be without it.
Leakproof, so easy to clean, keep coffee hot!! Love it!!
When I first started looking for a nice coffee mug that would stay warm, I wanted something that was different from a thermostat.
SipWorks have great color-ways for their Tumblers. I purchased two Tumblers from June-August of 2020 in White and Wood print. I've been cleaning these Tumblers in the dishwasher, and the Tumblers (the metal portion) are holding up very well. None of the print or color have chipped off.
Unfortunately, I can not say the same for the plastic lids. Do not wash the plastic lids in the dishwasher, they absolutely will crack. Wash or rinse the plastic lids by hand. The overall quality of the lids are lackluster, and not leak proof. Durability is just not there. After repeated use with steaming hot liquids, the cracks in the lid continue to spread until the entire lid cracks.
Luckily, Amazon sells extra lids with various types of closures: Open and Capped.
If you search for: "20 oz Insulated Tumbler Lid Splash Proof Lid Press-In Replacement Lid for YETI Rambler, Ozark Trail"
I ended up purchasing option: F (in 20ounce)
It works great.
Hot liquids stay hot for about 2 hours and slowly cools down to room temperature at around 8 hours. It’s honestly perfect for a full work day at the office. Excellent.
It's a 4/5 Stars for me.
Minus -1 star for the poor quality plastic lids.
Overall, I'm still very happy with both of my Tumblers and would definitely repurchase, just make sure to buy an extra lid.
