Review on 📸 Effortless Picture Hanging with the 10X10X29mm Square Measuring Kit by Paul Dobson

I compared 10 levels with a good "master" level and IIRC 5 out of 10 agreed with the master. I have no problem with that at this price - about $1 each. 5 good ones cost $2 each and I can certainly work with that. Regarding adhesion, I gave these levels a 5 star rating, but let me be clear: these levels do not come with their own adhesive. You MUST use double sided tape or something similar to stick them to anything. I used double sided tape and it's cheap and available here at Revain and elsewhere, as is most equipment and even some grocery or drug stores. I had to file and sand the ends of the tier to fit the shape of the unusual use I bought it for (not picture hanging). But it worked. There is extra plastic at the end and there is space between the liquid and the ends. After filing and grinding, the liquid did not flow out.
