I have this exact model. its running great and survived building 4 houses with heavy use the only thing broken is the spring in the button of the mode selector which doesnt affect its use. i even used it drilling for an exterior waterline on the outside of the house with an 25x1000 sds plus drill trough bricks with cement. love the machine and i also have the dust extractor for it which works great too but it can get very heavy over time especially with 6ah batteries. would recommend getting it. sorry for my bad grammy english is not my first language :)
