I sent an email letting you know my cords weren't working well never received a response Also your website needs to have more info on the different kind of cords and magnet attachments. I realized I bought 2 different types of chords but didn't realize they weren't interchangable...so now if I want to use the 6ft chord I would have to change the magnet which isn't easy nor convenient...your customer service is not good..and your website needs to be more clear... Especially for non techy people! I LOVE the concept of your product but you need work on customer service and clarity on your website....thank you
