The idea of a cordless is escellent - but it has to stand up - this one doesn't. Unfortunately, I noticed severe battery decline after about 6 months and then it just stopped working altogether. This is the worst battery life versus usage I've ever seen. I tried all the online forums, disconnecting batteries, clogging, charging etc. It probably lasted 2 hours total. This product is badly designed, poorly executed and a rip-off. Don't buy it.
