Ive had it several months now and am still on the original battery There was absolutely no way that is truly the best option across the board for all the relevant phone companies. For the same sandal! Thank you for having it available. I eventually took my shoes to a cobbler and had the insole area filled in. Connectivity is quite simple, the design is nice. I then used 2? 5x16 hex screws and washers to mount the frames to the boards and it is super sturdy with zero give or creaking when in use. Really well made especially for the price! Assembled and installs relatively easy, but sits too close to the exhaust. They cost a bit more, but.
