I originally purchased a metal bodied Fein tool, it worked great but it generated so much heat that I needed thick leather gloves to operate it for more than 15-20 minutes straight.
I traded that in for a Dewalt, Milwaukee and finally a cordless Porter Cable. The PC was the best of the lot, actually it worked quite well.
Then I moved on to a Fein MultiMaster...nothing wrong with that piece of equipment. Dependable, vibration free and powerful.
Finally, I purchased a Festool OS 400, nice piece of kit, very happy with it but just after the purchase, Bosch/Fein started to dick around with the "Starlock"..."Super Starlock"..."Ultra Gigantic Starlock", "Never Been This Big of Starlock" concept. Now, that whole thing was very annoying and still is, the memory persists.
Finally, I decided to purchase an OSC 18...Marketing finally wills out, that hurts because there was nothing inherently wrong with the OS 400 except that they started to obsolete blades which does make a huge difference.
