I bought one as the price looked good, and I had a 24V GBH a few years ago which was a real solid workhorse of a drill.
I submitted the following review to screwfix, but they havent put it up for some reason (there's a suprise)

This is a very poorly made drill.
I used to use a Bosch GBH 24V SDS drill, and more recently the Makita. Both out perform this drill
There is no roto-stop mode for chiselling.
The variable speed trigger does not work properly. It is all or nothing. At low speed I can stop the drill from turning by gripping the chuck in my left hand.
The trigger has a poor response time. When pulsing the trigger for screwing etc, You can pulse the trigger quicker than the drill can respond.
You have to move the side handle out of the way every time you change the battery, which gets annoying quicker than you'd beleive.
On the plus side, it is light weight, and comes with a nice box.
In summary, save your pennies a bit longer and buy a decent drill.
