Sonicrafter F50 4.0 Amp Oscillating Multi-Tool is rated 4.5 out of 5 by 21.
Rated 5 out of 5 by from This tool was perfect I bought my F50 almost 2 years ago and never used it. We have an old farmhouse and my wife got a dishwasher and there is no hook up for it. So I had to make nice cuts in 2 existing cabinets to fit it. My circular saw did the 4 roughing cuts. I used the F50 to finish trimming the cuts square and cut the drain and water holes in the floor. Also cutting the plastic pipe for the new fittings. I. Couldn’t have done a nice job with my reciprocating saw which I used on my last dishwasher installation. The light on my F50 was perfect for the darkness inside the cabinet. I am more than happy. Now to get 2 pcs of wood to finish the job.

Rated 5 out of 5 by from Excellent to sand and cut 2x4 studs. I used to be a dremel user, but i give a try since i was using the handy saw more than 2 years ago and still works like a champ. So i decided try a oscillating tool and i was very impress compare to my decease dremel tool. Hope long for last and i love the easy way to switch between accessories. Tried studs and notice very powerful didn't decease till the end.. Looks like wood eater. Very sturdy and nice quality tool, i would recommend a multipurpose tool like this must have to everybody.
