Do not waste your time or money on this Servo. They do not hold up. I just replaced mine on my almost new Big Rock. Servo started not holding zero/re-centering then died al together with a strong electrical smell. Spend $20-30 on a good Servo!
I'm a tool guy. More mechanics type tools than carpentry tools though. I have $50,000+ in mechanics tools! This is my first sawzal. We always had a "community" corded sawzall at the shop which I would use on rare occasion. What I'm getting at is I have no idea how I went so long without this saw!! I've only had it 2 weeks and probably used it 3-4 times around the house. It works awesome! I have all the other Bosch 12V like the impactor and driver. Those tools are AMAZING also. They hold up to professional use on a day to day basis no problem!! You can't go wrong with Bosch!
These blades are AWESOME!!! I took some worn out stock blades off my 60" 455 and put these on. COMPLETELY transformed cut quality to nothing short of amazing! You do not need to use a mulch kit to use these blades. It purées the clippings and virtually leaves zero windrow effect. Highly recommend!
