Saw this in the comments of the reciprocating saw deal. The 4.0Ah battery makes this the better buy in my opinion. The equivalent Ozito battery costs $69 and slightly smaller grinder $59 for skin only.
I wouldn't recommend this (or the Ozito) if you are going to be cutting steel or masonry all day but if you just do the occasional grinding/sanding it is perfectly adequate.
Quite a few other FERM branded products which are priced very well. Don't buy the blower though, I have the identical looking 18V Victa and it can barely blow dry leaves on the highest power setting.
I get it, we all want our tools, and have dreams of doing "all the jobs," but jeez this buying a tool for the occasional use is one of the many negative outcomes of our consumer society. Use once, often sits in garage forever after. Borrowing things from a friend (of a friend) seems a lost art. Not crapping on the deal.
