Easy to put in and take out the battery. Fast charging and the batteries hold their charge even when not used for a couple of weeks.
Trying to register the products proved to be a real pain. The kit I bought wasn’t listed on the website. Somewhat surprised and
unimpressed by the disinterested male who answered my call on the telephone “helpline”.

Just keeps going. Got the 4.0ah battery and it lasts and lasts. Driver itself is really powerful and works well so far no issues.
Haven't come across anything yet.

One of the best things I've bought. I've always wanted one but could never really justify it until I had a shed and long fence to build. It made short work of any size screw. Why didn't I by one earlier?
I want another one but the wife says no.
