I was in B * Q and tried out quite a few of their stock. Very worrying as most instantly failed the standard Davies test (i.e. find something long, straight, and seemingly level, put the spirit level on it, turn it end for end, put it on the same spot, and note any difference in where the bubble sits. Do it again on various surfaces, until you find the rare spirit level that reads exactly the same both ways on! Vertical surfaces also. )
Several levels of the same make gave wildly different readings on the same surface, especially B & Q own makes. I would like to see some of the structures anyone built with one - but at least now I know how that tower in Pisa got to be the way it is!
Eventually came across two really good Drapers, supposedly professional quality, in aluminium, with a milled finish, and very clear to read. Cost me about £45 for the two.
