I bought this with apprehension but today I really put it to the test and man did it do the job. I was ripping home milled 2X12’s and it literally blew everyone’s minds. I used a 4AH battery and literally used it all day while building a few things for the kids. I was waiting for the battery to weaken but it didnt. Once home I placed the battery on the charger and it was fully charged in about 10 minutes. Now I ripped 2×12’s, and cut I dont know how many pieces with this saw today and it never backed off. I wish it had a few metal parts where there is plastic but hey, 99 bucksand what it did for me today I cant complain…five stars all the way Thanks.
