Bluetooth connection was easy, the PC recognized it right away with no connection issues. very pleased with their customer service. After I got nasty athletes foot at my local gym, I wear sandals for that quick after workout shower. True to my size and love that the straps are adjustable. For us they work great until they die. I ordered 3X and its still flattering. This is not good for people who have wide or flat feet. Top and bottom buckle are related as far as strap length but even the best placement still meant some straps trailed. you will have to do the reverse of that and take the entire thing apart every time you remove this from your bike. 5mm phone jack option (preferably a 90-degree one) that would further eliminate typical problems (in order to keep the sound quality for my phone calls, I am forced to use Headset Buddy that needs frequent replacement, but it has no competition).
