The battery lasts 6 hours+ Thats great and recharge in case in about 30 minutes. My husband also got a pair and the same thing happened. Comfort: I bought these Danksin Loralie wedges and spent about 30 bucks on a set of orthotic insoles by Abeo. No big deal until 2 days ago. Allows kids to use their imagination to make any kind of bracelet they would like for their friend. Size: I studied its dimensions before I ordered it and used my tape measure to get an idea of size where Id be placing it, so I didn’t go into it thinking I was getting something bigger than I actually was. The zipper is extremely flimsy so I cannot even zip up the entire wardrobe which defeats the whole purpose. As for battery life I have used them around one hour at a time (6 times) with no drop off, great again. Would not purchase again It’s been 3 days now and no email no phone call, nothing.
