Ive just looked at Aldi for the 19th March, a damp tester for £9-99 does that sound cheap or are there cheaper ones, they say it is a 2 in 1 and looks ok
I've got one , it does give you a indication of how much damp there is , and you can get in tight spaces , i would say the buzzer type are better , but not so easy to use in small spaces .
I didnt think they could be so cheap, I think I will wait till next week and get an Aldi one, no post and packing plus I can take it back if it breaks down,
