easy to use overall but lock screen does have an intermittent lag issue where it takes 3-4 swipes to get past it. ***updated review: it has become the most inconvenient, phone controlling, battery hogging thing ever!!!! It seriously takes 2 minutes just to get my fn phone unlocked, then when i FINALLY get to use my phone, it takes over and i have to get past it 2 or 3 more times!!!! IM DONE!!!
