Is there one that actually works?
Being a cheapskate I'd like to buy a cheap one, of course. But all the reviews say they are a waste of time and that you "get what you pay for" etc.
But then it seems the expensive ones don't work very well either. I watched an online review of a Bosch one costing about £60 and that, too, was rubbish. And read a DIY forum, where people were complaining about theirs being useless, but they'd paid £70 for it, etc.
If they are all hit and miss I may as well get a cheap one and take my chances.
But I just wanted to know: does anyone have one (cheap or expensive) that actually works?
Thanks
