It turned up today. For an alledged 'B-grade' recon stock it was basically brand new in box, blades not used and still in all the original protective wrapping. Even the blow moulded box has nice metal clasps and a quality feel.
The tool itself is satisfyingly heavy and has a really solid feel to it. The gearbox looks really solid. Side handle and main guard are strong looking and appear to be removable/adjustable if you want. The only slightly flimsy looking bit is the clear blade guard but I suspect it is stronger than it looks.
Did about 10m of skirting today using a thin bit of ply against the guard to keep it the right height off the floor. Went through it like a knife through butter in no time at all. Didn't hit a nail, but nice to know if you do it won't matter too much. No kickback even when plunging in. Chucks a fair bit of dust about but then so would a big circular saw.
Ine potential downside is the cut is quite wide (2 blades wide in fact

). Not a problem in most applications but somethi g to be aware of.
Overall based on one day of use on wood, impressed. Feels nice, heavy and solid. In a few weeks I have ajob to do with metal racking like dexion, will see how it cuts that but I am expecting to be impressed.
