I was thinking that one of those would be handy when I walk the dogs out in the woods. A few branches removed would make the walk a little more enjoyable and easy to do with one of those.
Major improvements in cordless tool batteries and the tools themselves.......I had a flat tire on a semi trailer about a year ago and the roadside tire bubba that came out had one of these.....I was amazed.....A complete beast and cordless to boot.....Ozito is Chinese made and it is an improvement on a previous brand name, 18 volt power that seems to go forever, well almost, 3 years battery warranty and 5 years on the units, the pole saw will cut up to 10" diameter at a reasonable rate, same with the chain saw, an improvement could be made on the position of the safety start over-ride switches on the units, and the same goes for the 240 volt corded Ozito gear that I also have.
That small Amazon brand hand chain saw I did look at, that would be very handy for pruning and light trimming type work, I decided to get the cordless chain saw as being more to my now and then requirements.
And you have probably noticed the improvement in batteries in the last 6 years or so.
