XtremePowerUS jack hammer review

Review of XtremepowerUS 61116-XP Jack Hammer w/Chisel & Shovel Bits Heavy Duty Electric 2200W Demolition Construction Concrete Breaker Punch Drill. The good: I could dig 2 ft x 2ft x 3 ft hole in rock soil to plant a tree in 30 to 40 mins, earlier, auger machine failed to do this as rock soil is very hard. Excellent packing, easy to use, good boxes, fast setup. The bad: the middle handle is not strong and already lost its proper shape. Hopefully this should not be a problem.
