Excellent quality and so easy to put together only tool required is a hammer - no not to smash it - but to tap in the dowels. The screw driver comes with the kit. Recommend to everyone took me 20 minutes to build and I hate manual labour.
I bought this as just broke a part on my previous hand held, it is slightly heavier however the performance is 1 times that of the old one, now don't even use the plug in one as this is so easy to use and is better and saved money as box was damaged, though didn't matter as it hangs on the wall and not in the box!
