DazhuocsWater Bottle Handle, Silicone Water Bottle Sling, Carrier, Holder with Strap, Fits Most 8-40oz Bottles Stanley Cup Accessories (Purple)

This did not fit my Stanley cup but did fit a different cup I had so I kept it and use it.

sturdy and cute. I like it.

Installation was easy, just stretch it like a rubber band over the top and past the lid, then clip the handle onto the band. It fits my Simple Modern 40 oz Trek Tumbler perfectly. The handle strap is thick and comfortable to hold. My main concern is that even when only 2/3 full of ice and water, the band shifts up a little under the weight of the bottle. In person it’s easy to see the stress point on the rubber band by the clasps. Also, the claps themselves are quite thin, I have thicker clasps on keychains which don’t have to support as much weight. Overall, it works for now, but I don’t feel confident that this will last long for me. I recommend it if you don’t keep your water bottle too full or packed with ice.
