First, this is a good little usb cable. It is just the right length to connect a phone to a laptop. The magnets that hold the ends together aren’t very strong though, they definitely wouldn’t keep it on a key ring for very long in a pocket / purse.
If you’re really interested in this product, I’d recommend heading over to the mothership and taking a look there, I purchased a 7 pack for about the cost of this single cable. Not much of a deal to be had here unfortunately.
