I bought two of these. Pulling the band/strap off to charge the first device took around 20 attempts over the course of 2 hours. Getting the strap off the other device for the first time was even worse, requiring double the time and effort. Once the strap is removed and the device is charged it all seems fine. Removing the strap again seems tough, but reasonable. You'll just have sore fingers for a day or two from first removing the strap.
