Brought this drill to replace a GSB18v 28 li that was 3 months old and could not drill any bigger than 7 mm holes in aluminium sheets without stalling. This drill will rip your arm off compared to the other and 13mm is no problem with it no stalling and the anti kick back works well also the battery lasts longer as this drill is brushless.

It is a good power tool but I am not satisfied because it came without the side action handle Louise Lister

Very happy with purchase for handyman use
My previous brushed motor version of this suddenly stopped working but maybe i was overworking the tiny motor, so thought worth one more try, will not push this model with too much hammer drilling. This does feel and look like a modest improvement, heavier and more compact with a valuable longer secondary handle. Influenced by having only this one 18v cordless system into choosing what probably has more affordable alternatives.
Good strong drill. Used daily for commercial electrical work. So far very capable. Bluetooth is pointless, only tried it because it came with the drill otherwise wouldn't bother.
Bought this to replace an 8 year old Bosch that did a lot of heavy duty work. This has more power, is slightly smaller & lighter & I hope will last as long. Pleased with the price
This is a nicely designed drill. In my opinion one of the best on the market. All the essential functions inc hammer, and many screwdriving torque settings. Brushless. Very comfortable grip especially for smaller hands. Good balance especially with the new CORE 4Ah battery. It's a bit top heavy with a 2Ah pack. Comes with a quality Rohm keyless chuck, again a mark of a premium drill.
Definitely worth the money but only time will tell hence only scoring good for now.
great drill, huge power, very silent comparing the other brands, easy to use, great features, kickback control saves lives
