5mm jack is too big to plug in. 6 Monalte alt gewesen bis sich der klinkenstecker aus der Kabelfassung sich löste. I have narrow feet so the middle strap was a tad loose but that’s just what I deal with in a lot of shoes and it doesn’t even look bad! Only uses one AA battery and did great with using a rechargeable battery! Its bit low for a 510 to sit on to change shoes. Love this thong sandal These were super easy to put on, are exactly as described and I even mad ea mistake and had it off center and it allowed me to take off and reapply and it still sticks fine. I used to take Google Assistant for granted but after using Bixby a few times I find myself with a new found appreciate for my Google Assistant. Not terrible but I wish they didnt. the size is as I expected
