In theory amazing, in reality not so good
Just got the MagSafe rings with my Energy Pack. Easy to apply and seemed rock solid after installation. I set my Switch 2 down to charge and when I went to pick it up, the Energy Pack was on my desk with the ring stuck to it instead of my Switch. Clearly the heat from Energy Pack is too much for the adhesive. It just loosens and comes off. This is too bad because this ring is one of the main reasons the Energy Pack is so convenient.
