      Comments about 1-1/8 in. SDS-plus Rotary Hammer Kit:

      I gave a 4 only because I have not used the product. Sorry I cannot tell you about it. I got sick right after I got it and have not used it yet. I have bought 4-5 items from CPO and they have always been very reputable. They stand behind their sales. I had to return one item and theyu handled the return well.
