The Enearco Rotary Hammer Drill arrived on time and was in brand new condition enclosed in its own carrying case. I have used this drill for about 2 weeks drilling holes in a very large bedrock that I am in the process of breaking up. The drill has been a real workhorse and has worked flawlessly drilling over 100 holes at various depths between 6" - 18" at 1" diameter. I have 2 reasons for not giving a 5 star rating. 1) Lack of reverse rotation. This would really help when the drill bit gets jammed to get it unstuck. 2) The function switch is difficult to change with only one hand. You need to depress a button in order to move this to another function and more often than not, you need to use both hands, because of the button. These would be 2 recommendations to improve this otherwise great drill.
