Berserker 1700W 30-Pound Demolition Jack Hammer with 1-3/16" Hex, 14-Amp Corded Electric Heavy Duty Demo Chipping Hammer Concrete/Pavement Breaker with Carrying Case Flat Chisel Bull Point Chisel

This thing is an absolute beast! I had a problem with trigger sticking on the unit but Amazon sent another one promptly - I could not say enough good things about this jack hammer! It’s amazing! It’s heavy but it went berserk on my concrete pilings. It broke anything I threw at it…

Had to tare up a side walk at our house. I was going to rent a jack hammer but the price for one day rental was more than the cost of this product. Liked the reviews. This unit is terrific. I broke up the side walk which was 6” thick in no time. Recommend this product 100%.

Great price, great durability. I’ve put it to the test on a commercial concrete demo job for 1 month so far.

I've used this tool for a few different project so far, and it is a beast. Seems well built and just keeps working and working on whatever you're trying to break up. I'm so glad I didn't get the vertical-only jack-hammer, because being able to use this thing at an angle can be extremely useful. It worked on a 6-inch concrete driveway and a boulder that we dug up in the yard. It does take some control and strength to keep the machine pointed in the right angle as it pounds away. You certainly need to be physically in good shape and have upper body strength to wield this tool effectively.

Used it for several hours breaking up an old concrete walk. Some of it very think. Will it last? Who knows. But it seems well built and did the job it was purchased for. Everything else is a bonus.

my buddy lent me his 90 pound $1500 m*kita jack hammer. it was a bit heavy for me. so for less than a quarter the price i got this jack hammer that was half the weight. so far it performs as well as the m *kita and is easier for me to use. clearly they copied the m*kita design down to the color. they have come up to speed with their cheap copies. good for me bad for m*kita.

I had a large tree stump in my yard the I was trying to remove but the roots had grown between the layers of the large rocks under the stump preventing me from removing it. I used this tool to break up the rocks and undermine the stump enough to allow me to finish the job. The rocks were no match for this tool. It is fairly light and maneuverable but heavy enough that you don’t need to force it through what you are trying to break up. I cannot speak to the longevity of the tool and whether or not it will last, but it seems well built. For the amount of times I will use it as a homeowner, I feel like it will probably stand up to that use without issues.

What the other 5-star reviews said. This demo hammer gets the job done. It took me some time to figure out the right technique but once I did it works great. It's heavy and I'm getting quite a workout just moving it around but it does the rest of the work. I bought it to break up some concrete that I thought was 4 inches thick. Turns out it's 6 inches but the Berserker is undeterred. This job has already taken me 3 days so compared to renting a demo hammer it has already paid for itself.
