Pinless Moisture Meter for Non-Destructive Moisture Detection in Drywall, Wood, and Masonry

Hello amazon buyers , please don't buy this moisture meter , its absolutely rubbish , its a toy , apparently the pears on my pear tree are dry but my double glazing window are soaking wet , and i am talking about the glass not the frame lol .A bucket full of water is quite dry aswell , who would have known ha ha , I will be returning it ....
