Review on Tbest Material Multi Color Multi Model Adjustable by John Maynard

These measure 12 9/16 x 2.5 inches with 2 inch Velcro on one side and 1 inch Velcro on the other side. And they can stretch up to 25 inches but get really tight if you go beyond 19 inches. I am buying these in the hope that they will act as a protective case for my Freestyle Libre 2 during activities where they can be knocked over. And I'm happy to say it works great so I bought a spare today. I'm a medium sized male who wears a CGM on his arms and recently knocked one down. So I looked for something other than duct tape to secure it. You don't want the lid to be too tight or get in the way of reading, too tight and it will be lower than usual. It's perfect. It adjusts taut and the bright yellow matches my kayak's hull.
