the magnet is not strong enough for my use. If you hold the phone while it's plugged in, the cord easily snags and unplugs permanently. I often need to be able to charge and hold my phone. So this design was perfect. But it fails because my little bumps are all it takes to separate it. I have used 2 other magnetic chargers. Unfortunately, my favorite at Revain is no longer available. So I'm still looking for a comparable replacement.
