I had the smaller lightweight version of this that came out first, then swapped for this in the end. I find this one with the extra bit of impact energy is a bit more capable with doing chisel work. I use it with my 7ah ProCore batteries, it definitely is like having a mains SDS drill, but cordless! Even though it looks a bit 'boxy' it is actually really comfortable to use and very purposeful. It surprises with it's performance considering it's only on the 18v batteries. I love it!
Adam electrician I use it every day and so far have had no issue.
It's just as good as the 36v one I used to have and miles in front of the older model 18v.
Very happy
