These flip fops leave black stains if you step on drops of water in the kitchen area or bathrooms. Its fine that it doesnt have a battery case like on Apples Airpods. Most strap sandals have a toe strap and a separate ankle strap that dont interact with each other but this sandal just has one z-shaped strap that moves around a lot. With that of a price, I expect it to be a lot more of a punch. This seems to be a common theme with add-on kickstands so opted to do some surgery instead of look for a replacement. Not sure how much softer the "soft bed liner" is, it does not seem any softer than the regular footbeds, and I read that Birkenstock Express will not be able to replace the soft footbed liner, so that is a bummer. Sound is now crappy in the speakers. It broke off when I tried to disconnect it from my phone. And, if you have fallen arches, the slight heel will help keep your arch supported. The volume is way too low to be useful on the road.
