“Great product my second purchase from this company first XL I purchased. My biggest concern is the lid the opening is smaller than a Redbull can but does have give I tried it on a 18.6oz Monster rehab can and couldn’t get the lid over it enough to screw onto the Frost Buddy because the can was flexing too much after trying a 19.2oz Monster can this morning I was able to get the lid onto the can but took a lot of force so I recommend not doing it with the can open, after removing the lid the opening seemed slightly deformed my concern is over time the lid not holding too well but only time will tell. I will be ordering other products from the company though.”
