I’m am super impressed with this product I was happy to see someone selling a better version of this product. It’s durable. It actually does the job as advertised. I was able to take this cup put my Starbucks Trenta in it go on a very hot day to the fair from 3 o’clock in the afternoon till after midnight. I still had ice now mind you I did drink my drink, but I added two more canned pops. Yes they were cold, but I never added any more ice, I still had the original ice from Starbucks in my cup. I’ve never had a cup do that before so I’m super impressed I highly recommend this product. Keep up the good work
