Milwaukee 2626-20 M18 18V Oscillating Multi Tool

Overall I'm mostly satisfied with this multi tool. It cuts my hardwood floor very well, as far as multi-tools go. There are a few things that bother me, though. 1. The tool does not come with a battery or battery charger, which ran me $200 more than I was expecting. (My fault I suppose?) I would have opted for one with a power cord if I knew. 2. The battery is very difficult to get out of the tool for some reason- I have to pull very hard. 3. The product does not come with an adapter for the oscilating tool bit, which helps hold it on. I would not have known this while purchasing. Why would I? Also, it just comes with one blade, so it will be back to the hardwood store again. 4. Also, the battery, although it charges fast, it also runs out of battery within 15 minutes of using. I think I could have bought a bigger battery? Not sure- but the one I got goes quicker than I like if I want to get the job done.
