The thermal camera is much better than the Fire 6 which I returned and at this price I can endure the copper coloured trims. Case and glass protectors are available, they improve grip and protect the camera a little. Probably the best value thermal phone on Amazon. It's not exactly pocket size but that's kind of the point with these, big battery justifies the size. I read it's a good idea to respect the charging ports as they are a pain to repair, use a cable with some wear on it so it's easy to connect. (note there's no wireless charging)

This phone is so powerful and it charges like a nasa ticket taking off 😄

Best phone but too heavy, I would give 10/10
