Spirit levels ? Are they all of the same muchness. Lidl have a set of three going I was thinking to keep in the cupboard. I have a small 40cm Stanley* one already need something longer really
You can easily test them once you do buy them (doesn't help in the lead up, but means it's easier to trust once they do).
Set on a surface that they give a "level" result for, flip them round, if still level then they're OK. If level one way round and not the other, bin it.
