Customer Reviews

Great socks but the app is useless


I own two pairs of Lenz socks with rc1200 lithium packs. The app will not connect with either pair or with an iPhone 6plus or a 6s in iOS 10.2. It used to work with my 5s. My experience echoes all of the previous reviewers. When I contacted them about this known issue they threw Apple under the bus basically telling me I was on my own. Wrong answer. This is a premium price to pay for sloppy quality control and bad customer service. A double slap in the face



I spent a fortune on the socks but now have to pay for the app! The app will not recognize the battery packs! Total waste of money.

Does Not Work!

Outlook Task Sync Wows

Like other reviews, it does not connect with sock warmer battery blue tooth as advertised. Poor quality app. DO NOT PURCHASE!
