Bests & Worsts Reviews from Amazon

A very nice looking tumbler that does its job well. It does heat up a bit, obviously, but it never got hot enough to hurt me. If you’re needing something to take your drink with you without having to wait, then this is a good option. The few complaints I have are as follows: 1. The caps are smooth which makes it very difficult to open. Especially when the drink has cooled down some and creates this weird vacuum that ends up also sucking the o-ring out. There needs to be some sort of texture or knurling added to future versions. 2. Idk what the normal cool down time versus the cool down time of this tumbler. But, my tea cooled to room temp in less than 4 hours. This was while using the sleeve, as well. 3. The strainer doesn’t keep all the dry tea in. This isn’t too big of an issue and could likely be remedied by shaking the tea around a bit before putting the strainer back into the tumbler.
