This thing is pretty awesome. To be able to see what's going on in inaccessible areas, and look around, is awesome. First saw this on a YouTube video from the channel farm craft and it looked awesome. The video isn't bad quality. It's a whole lot better then trying to look through a tiny hole with your eyes. Although under zoom it gets worse depending on the zoom level. The controls were easy as pie. I didn't even need the instruction manual to figure it out. Mine came with a full battery and a 32gb micro SD card. I can always pop the sd card out of the slot, on the side of the lcd screen and upgrade it later if I need to. I got mine to see inside my air compressor while I clean it out, and prep it for coating with liquid silicone. Trying to make my new Air compressor last 20+ years and not ever form rust in the tank and possibly EXPOLDE! This endoscope will do great although, I wish they made the cable removable and sold a longer cable or include one a foot or 2 longer. It's only about 3 feet long. Besides my complaints this thing is awesome. So many uses and much easier then endoscopes you connect to your phone, if you can get those apps to work. The 2 I have won't work with my newer galaxy only an older one. You won't regret buying this one!
