T TAKMLY 5.5mm Endoscope Borescope Inspection Camera with Light for iPhone, OTG Android Phone, Snake Drain Scope Cameras Bore Scope Borescopes, IP67 Waterproof 16.4FT Semi-Rigid Cable

It was well worth the 20 dollars spent. The picture was crystal clear and the app worked great! This is one of those devices that when you need it, it's great to have in your tool chest!

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!

Let's be honest, folks, this is a 20 dollar camera. Don't expect 4K quality from it. That being said, this is a great camera for simple inspections. Mine has already paid for itself in a hollow-body electric guitar that had a buzzing sound on certain notes. Using this camera, I found a wire that was just close enough to the inside of the body to vibrate against the body on certain notes and chords. Using the camera, I moved the wire further away from the body and around another wire to keep it from hitting the body. No dis-assembly required!Now, for those who are trying to use it as an actual endoscope, again, it's a 20 dollar camera. If I walked into a doctor's office and they pulled this out to examine me, I'd be out the door pretty fast. It's a low-end inspection camera, folks. A Doctor's or Dentist's Office should be able to afford a better, medical quality camera for internal work with humans or animals. At least they should, considering how much you pay. Why it's sold as an endoscope is beyond me.As another reviewer said, the "nExt Camera App" from the Google Play Store seems to work perfectly with this inspection camera. It loaded right up and has worked fine from day one. Just make sure you Android device is OTG capable. There is an app on Google play that will check you device to see if it is compatible, but I can't remember the name. Once the phone was checked, I deleted it.I've used this on guitars, computers, (what is buzzing in there?), power tools, locating a dropped tool inside a car door, and seeing how wires are routed on top of the car's headliner. It has hundreds of uses if you understand it just let's you see what you can't normally see and it's not a high quality camera. You are not going to shoot the next version of "The Fantastic Voyage" with it.But as a quick and dirty inspection camera, it works just fine.

I got one of these and it did not work on a laptop or my phone. When I plugged it into a PC USB port, I could see video OK but any touch to the USB cable and the video would black out. I could never see it again even if I unplugged and plugged the USB cable back in - that happened on 2 laptops and 4 USB ports. It did not work on my Moto3G (Android 6) with any of about 10 apps. So it was broken. I returned it - the cost was $22.67 and the refund $17.83 which I did not notice. But it was BROKEN!!!! So I returned it and got a replacement.The second camera worked OK on every laptop on every USB port. Great picture - I was happy. But then I tried to get it to work on my Moto3G (Android6) using all of the recommended apps and a few more in the goggle play store. None of them saw the camera. And I verified that the app had access to everything it asked for (camera, storage, etc). Then I went back to the laptop thinking maybe I had broken it. Still worked great on a laptop. But I really needed this to work on a phone because it is just too cumbersome to drag a laptop around along with the camera where I had to go.So then I thought I would contact the manufacturer - maybe they had some experience with the Moto3G and would have a specific list of apps for me. I could not find an email address or phone number so I gave up and decided to return it. I noticed my $22.67 camera refund was $19.26. And when I checked the first order I realized I was not refunded all of my money for a broken camera.So it cost me $4.84 to return a broken phone and $3.41 to return a phone that was falsely advertised. So do not assume that Amazon refunds your money. I have found several instances where my 2 day prime delivery changes as soon as I order. So double check things.Update: I asked if anyone had gotten this working with a Moto3G Android 6.0 phone and received a number of responses saying others were unable to get this working with any of their Android phones - a total of 16 phones, many, many apps. So if you want to use this on a cell phone you should buy something else.
