In general, price = quality. Bought the second, the first took a year ago for the house. Cheaper with fixing the position of the seat at will, I have not found. Naturally, you need to save on something. Hence, not the highest quality microlift (it has been working at home for a year, at work - a month and goodbye) and felt mounting bolts in the seat (at 76 kg. Weight). By the way, this was not felt at home with bolts.
