Rockwell 18V Angle Grinder Skin RD2923.9

Just a piece of Junk – Purchased a Rockwell RD2923.9 18v 115mm Angle Grinder from the local Home Hardware store and it kept stopping all the time. I purchased another battery so I could keep using it but guess what?.... Yes that was the same, so I put it down to being a faulty grinder, rang Rockwell and was told to take it all back to store for replacement. Local store replaced the whole lot and I used it today (26/11/2020) and it's no better. Both Batteries were fully charged before using it and it still stops after around one minute of use. This is NOT satisfactory and I think all items that do not operate as they should, should not be allowed to be sold to the Australian Public. Will I purchase another Rockwell product ? ..... Answer is very clear ..... NO.
