I dont really use Oscillating saws too often but when I bought a bunch of new Milwaukee tools I decided to get one since they are so handy for light and finish carpentry. I thought it was odd though that the designers would go with a switch and a speed dial over a trigger since you can have much more flexible and smooth control over that kind of a tool with a trigger than a switch (at least to me), and its also potentially safer.
Another, much more serious problem, has to do with changing the blades. I found it strange that this tool wouldnt have a tool-free quick-change mechanism for switching out blades.
Finally, the last problem might also have to do with the blade but it seems as though the tools blade gets stuck very easily, it doesnt take very much for the blade to catch and stall out the motor even on the highest setting. It just seems as though there isnt a lot of power being delivered to the oscillating rotor.
That being said Ive been impressed with every other Milwaukee tool I have, especially the seemingly invincible Fuel line.
