I have a Raspberry Pi 3b, no plus. Others may have problems with other models, but with 3b it fits perfectly. It's pretty incredible. It is made of solid aluminum and acts as a large heat sink. It fits perfectly and in my opinion it fits so well I thought it was an OEM Raspberry Pi product. What I like about it is that it covers all the exposed areas of the PCB so you don't have to worry as much about handling. It also adds a bit of weight to the Raspberry Pi, but not in a bad way, it doesn't get pushed around as much and it feels more like a solid product in the hand. I had a previous Raspberry Pi and got a plastic case for it from another company and didn't really like it although it did the job of keeping it closed. But this product serves the same purpose and makes up for anything I wasn't happy with the other product. However, contacts remained open, but for me this is not a problem. Since I don't overclock, I can't say anything about the cooling performance. But I'm sure the huge heatsink and surface area would help quite a bit for something like this. I think they sell a fan version if you like it.
