Review on Reduce Cold 1 Handle: Transform Your Stainless Steel Tumbler into a Travel Mug! by Danielle Miles

Firstly this grip barely fits my glass (it's not one of the glasses this product was made for - Primula Ice Cap) but it is one of the very few options. When I put it on it was snug about a half inch below the rim of the cup. Everything was fine until recently. The interior lining could no longer hold the glass more and more often. It was time to gently hand wash it again because it was gross, so I did what I usually do. I later put it on my mug and when I picked it up, the handle immediately slipped off! 34 ounces of tea on the kitchen table. Sheet. So if you measure your cup and this product basically fits, be aware that you have close to a year before your cup slips.
