The more I wear them, the more I like them!
The battery charge in the Spryng lasts a long time. I've driven the 3 hours from a day of skiing wearing them through 11 cycles. They feel so comfortable, I find the cycle has stopped and I'm still walking around the house with them on. The fact they are mobile and hand free compared to other massage devices is a huge asset. I definitely recommend buying them with the knuckles to get a snugger fit and think they should automatically be sold as one unit to avoid any confusion. Overall I find them to be a great product backed up by responsive customer service.
