Review on YJJelt 40X40X20Mm Conductive TEC1 12706 Thermoelectric by Peris Auditore

They are exactly as expected. 40x40 exactly, I put some Peltier TEG in the back and it fits perfectly. They have a sticker on the back that hopefully has a small thermal pad on it (but I have a feeling it's just glue). I think the design is great. They came in a small box but were unwrapped. The guy who delivered the package actually threw it on the floor while I was watching and the box broke. But I don't need it. I don't do anything very specific, so I'm happy with them. Many Thanks.
