I bought this because another reputable make of jigsaw I had wouldn't cut in a straight line! (and it wasn't me ... the blade didn't point forward!) that one had a quick release blade clamp too so I was hoping that this wouldn't have that problem. It's fine. I was a bit surprised to find that the auto select is really just a speed control, as I was hoping that you could control the speed with the trigger which you can't, however having a speed control on the side is actually quite good as you can control it with the other hand without loosing grip, (which is what happens when I've used a jigsaw with a knob or dial at the top, then you can't can't change the speed and hold it properly at the same time). The speed control isn't continuously variable as it's notched but it gives you enough control.
Anyway, very nice machine, feels well made and takes both types of blades which must be good!
