> 3 dayI have a Tervis brand stainless steel tumbler that I drink out of all day everyday. I was tired of the loud clank it makes on the countertops whenever I set it down. Decided to give this boot a try in hopes that it would fit my cup. I’m ecstatic to say that it fits perfectly, doesn’t hide too much of the design on the outside, AND has significantly dampened the sound when I set the cup down. It is exactly what I wanted!!!!!

> 3 dayeasy to put on, got it so I wouldnt scuff the bottle and so it wouldnt make so much noise as I set it down so it definitely does the job.

> 3 dayThese are a nice little addition to my iron flask. They seem to stabilize the larger 40oz bottles and keep the bottom from getting scratched.

09-06-2025This is a must have if you’re a clutz or have little kids. My toddler has tossed my bottle all around and not a single dent!

08-06-2025This didn’t stay on the 64 0z Iron Flask I purchased at the same time. I noticed it wasn’t on the flask so went in search of it, found it and put it back on. A bit later, I noticed it had come off again. That time, I wasn’t so lucky, lost for good. Waste of $10.

> 3 dayGreat for the bottom of my iron flask bottle, and looks great too. Only issue I have is that its a little loose and comes of easily. It wont slip off while youre drinking, but itll come off easily in some scenarios like a light bumping of the rubber. Though, thats what some people may like about it to easily clean it.
