I have two M12 NON Fuels both shit the bed , I have 3 M12 Fuels and 1 shit the bed , I have the M18 Non Fuel and the battery keeps dismounting so Im torn If I want to get another. I do use them a good amount but overall more of mine are broke then not broke and I hate having to mail tools in and then find out stuff isnt covered. Been seriously thinking of going back to Ridgid.
