USB Endoscope 3 in 1 Borescope 5.5mm Ultra Thin Waterproof Inspection Snake Camera Micro USB and Type C for OTG Android, PC, Notebooks Windows Mac with 5M 16.4FT Semi-Rigid Cord with LED Light

This borescope worked well for me when connected to older Nexus (Android) tablet. I was able to look thru sparkplug hole inside engine cylinder. The camera has LED illumination, and the brightness can be changed. There is no focus control but image sharpness is good enough to see internal surfaces being investigated. Images can be easily saved. This tool is well worth the price.

The Seesi USB Endoscope seemed with good build but after trying it for the first time it didn't work. Plugged it in MacOS and Windows as described on their website, and used the apps mentioned with no success. The Endoscope lights are ON when plugged, but the camera seems not being detected by the MacOS/WIndows. The guidance between Amazon and their website and the instructions within the package are somewhat inconsistent and misleading. In the package instructions they say it works on iOS, but on their website and Amazon product description they say iOS is not supported. Also conflicting suggestion on which app to use on Andriod.

I bought this camera to look inside my classical guitar to see what was buzzing. It works well. I use this camera on a Linux laptop with a USB-C port. It works plug-and-play out of the box with the Cheese photo/video camera application, which is all I need. The video can lag when moving the camera quickly, but it's not a big deal to me. The lights are bright and controllable. The images are clear. The focus distance works well for looking inside a guitar. Nothing is going to be super easy about threading cameras around awkward angles, but the cable bends and holds shape well, which helps. Just trying out the tools, the mirror attachment is useless, is out of focus, and doesn't even really reflect. I had nothing to hook or probe, but they might do light work.

The video quality is pretty decent considering how inexpensive this was. Followed the instructions and downloaded OTG View for Android. Plugged the camera into my phone with the USB-C adapter and picture popped up right away. It lost a star because the attachments don't stay on well. The collar is too loose and made of hard plastic so it doesn't actually grip the camera housing. I had to use some painters tape to tape the collar and attachment to the camera to use it. Other than that, it's a great value compared to cameras that are usually 5x the price.

This came is handy when I descaled the boiler in my espresso machine. You obviously can't really see inside of a boiler so I purchased this to get a look inside, since descaling is a big and dangerous job on these expensive machines, you don't want to descale if you don't have to. This camera showed me I absolutely needed to, and I got some really good before and after shots along with being able to see if you got all the descale solution out of the boiler. It was hard to find an app but they do have some on Google Play that are compatible. It's length is over 15 feet, it's easy to use, functions like a champ, and gives you great quality pictures like you see I posted. There is no battery and just hooked into my Samsung Galaxy S21 Ultra. Definitely recommend!
