Harbor freight electric 16 inch chainsaw review

I have an EGO brand I bought from Lowes a couple years ago. A couple of my neighbor's trees fell on my property and I helped cut them up. It has a 5 amp/hour battery and went all day on the single charge. It cut like a hot knife through butter. I was surprised it lasted that long but after I thought about it, I was only cutting for a few seconds at a time so it wasn't running constantly. Another plus is the different EGO batteries all interchange. If my 7.5 amp/hour mower battery doesn't quite last for my entire lawn, I just pop in the chainsaw battery to finish.
