I have the Bauer 20 volt pole saw and in my opinion, it's a dandy. Has a built in chain oiler and easy chain tensioning (single knob) as well. Got mine on sale on the ITC club flyer a while back at half price. Just run the Bauer 5 amp batteries as I have a pile of 20 volt Bauer tools and none have let me down yet. Only have one DeWalt tool left and when it expires, I'll ship it off to the landfill anyway.
Lets see, besides the pole saw, I have the 4.5" angle grinder with the newer motor, a 1/2" varible speed drill, a 20 volt hex impact driver, the oscillating sander and a 1/2" drive impact wrench. Got all of them on sale, ITC, Not commercial grade stuff, just home owner grade.
