Thanks for the helpful replies. I didn't look at the video. We bought something from this person before, and I don't think she was deliberately lying. Maybe the person who used the saw also chopped up wood with nails in or something. The blade was damaged and some of the points were missing. Anyway, someone bought it! Have since checked out the shop, there is one left at 270 euros, (about 180 online + delivery) but OH said it looked faulty. We waited ages to ask someone if they stock the blades and how much, but gave up in the end. There was a new batch of wood saws that didn't look any more substantial, at 450. Reluctant to buy online in case of problems. We had that with a dehumidifier and the company never replied to us, or to the local shop that they supply with stock.
