Review on Ferrite Magnetic Squares Adhesive Rectangle by Athenasby Whitney

Unfortunately, as much as I want to rate them as excellent, this is the third time out of four that I have received the exact same set of magnets and half of them in the set were not good. no 3M adhesive pad. I immediately used the self-adhesive ones on my current project and will be using the adhesive for my other less important smaller projects. The adhesive method is not as reliable as 3M pads. Considering I bought them specifically for 3M pads which "almost never fail", three out of four isn't a very good track record considering how easy it would be to assemble the product properly and package it properly , so everything is sealed with magnets 3M.
