I do a fair bit of DIY and have always found it difficult to properly tighten drill bits when fitting them into a key-less chuck. I was therefore attracted by the fact this drill advertised 'one handed bit changing'.
The drill is fairly heavy in comparison to my old 14.4 V Black & Decker and that is down to the battery, but as it drills so much faster than my old drill, the weight is not an issue at all in use. If anything, the old drill felt much heavier as it took so much longer to drill a hole. And I have found tightening drill bits to be an absolute breeze.
This really is a very good drill and I cannot recommend it highly enough.
