These were my vacation shoes. It is more structured than my other Go Walks. You can assemble them and put them in the refrigerator. My biggest gripe are that the stock tip are fairly small, so I swapped to some more standard Sony types silicone tips. My only criticism would be that the diy runs on the wrist and you end up with black marks but it doesn’t bother me at all really 👍👍 When you seal the gasket properly they are in there nice and tight- to the point that I have trouble opening it with one hand. The instructions also call for a T-30 TORX bit & Torque wrench as a required install tools. Usually its easy to just find my place again though. It is easy to carry and the battery is durable. b.
