I personally haven't used but did read a german review can't remember which one and if I remember correctly, you can cut something like 100m of 22mm chipboard flooring. I thought was quite impressive, but can not confirm. It comes with 2 batteries where the hilti only come with one. It is a kilo heavier than the normal version and will be extremely well made. I have thee kss400 version which I'm extremely happy with for general purpose work. It can be used with the mafell rails. Also something to be aware of is if you get get the ksp55/36v it will not fit onto the cross cut rails as the base is slightly different the kss400/36v but the saw unit it's self is the same. Personally I only think it's worth buying if you are struggling to get power like on barret, Taylor wimpy them sort of major house builders where they don't supply power and you need to have a generators. Also a lot of them type firms are not allowing you to use a generator unless you have drip tray. Basically they are wanting everybody to go cordless so no cables acting as trip hazards. I know it's a lot of money but by the time you factor buying in a decent new generator cost of fuel to run no cables it possibly for the tight sort of work make sense. That would be something you would have to decide for yourself. The best think to do is contact Nathan at NMA agencies tel 01484400488 he might have a demo machine you could try for a week or so at no cost, but you would have to speak to him on that. As it's a lot of money I think you're better trying first then deciding what you want to do
