Cutting wood takes too long. Cutting metal (cuting nails) takes much too long versus a Dremel. And it's LOUD.
I bought a Menards-brand Li-Ion cordless model. Is there THAT much of a difference versus the others? I can't find a review that implies cheap oscillating tools are necessarily worse than, say, Rockwells.
I know that cheap power tools aren't as good as expensive power tools. But when I buy Harbor Freight I get about 80% of the effectiveness and ease-of-use.
