There's always the issue of warranty and defects when you buy used tools. I once bought second new tools for dad and they ended broken in less than 3months. So I eventually bought him new power tools that are more than 2 years with him now.
hi! I recently bought new tools for dad. I bought him a Cooper Lighting LED Might D Worklight and a Genesis GMT15A Multi-Purpose Oscillating Tool. I think these are really great tools and he was really happy having them.
