Battery slippage
Tool works great for getting up old linoleum. The only issue is all three batteries I have constantly come loose. Turn it on and the minute the blade touches anything the battery slips down about a millimeter and the tool shuts off. I either have to hold my palm against the battery or constantly push it back in. The tool is new. 2 new batteries and 1 older one. I would by the 18v if I could do it over again. Maybe avoid this battery style all together.

    OK on a Budget
    The Milwaukie 12V system is pretty basic and the method for holding the battery in place just doesn't cut it on a vibrating tool. The battery falls out in use, so it has to be taped to the tool. Still, for the sake of a cheap tool, I can do that. Suggest the corded version if you want to use it regularly, or their 18V if you can spend almost 3x as much. I have two 12V and two 18V Milwaukie tools. The 18V tools are good. This is the last 12V Milwaukie I'll buy. I like Makita better.
      Very good construction and saved allot of time ! It’s...
      Very good construction and saved allot of time ! It’s worth the investment for sure. I installed 3 on demand water heaters with allot of precision on the cut. I think as well the light aids in marking cuts visible Very good product.

      Must have multi tool
      I’ve been a long time Milwaukee fan and this multi tool does not disappoint. I’ve used it for just about cutting anything you could imagine. Makes cutting for electric boxes in shiplap a dream and drywall like cutting hot butter. If needed you can cut a 2x4 no problem. The trick to a quality cut for what your cutting is the blade quality, there expensive but worth every penny. If you buy cheap blades you will not like it. It can be a battery hog so have a few battery’s and a 4 amp hr battery is best for big jobs. It’s a bargain and the possibility’s are endless even cuts pvc and copper. Highly recommended this tool.

        Price doesn’t reflect quality
        Had for a few years but only used a handful of times for small DIY projects. 1 star for ergonomics. Definitely not beat up, even the bag is still clean. The positive side of the plug got stuck in the battery. No idea how this even happens, battery gets pulled straight out. Tool didn’t even pay for itself.
