Phone endoscope camera

Has anyone tried one of these that can connect to android or iPhones. There are many on the market from £10-£50. The reviews vary as well as the picture quality. I would like one to use on my bike (1977 R100RS, just had it one week) so need reasonably good resolution/picture quality. Also to be used around the house (drains, underfloor boards, etc).

If you have bought and been satisfied with picture results I would appreciate your recommendation

Thanks

I have one and I suppose it can have its uses if in a tight fix. The focal length is fixed so under certain circumstances, your image may not be 100% sharp.

One thing I found was that you need a phone (android) that has OTG (on-the-go) capability, and some of mine didn't!!
This basically means that your camera will work via the micro usb (charging) port on the phone.
Just mt thoughts

I bought one to use with my iPhone.
The quality is outstanding for sub £20 (when I bought it 3 moths ago)

It works well but just bear in mind that the focal length isn’t too great. By that I mean that it’s great for looking down pipes at blockages that are right in front of the lens, etc, but passing it through a hole in the wall to checkout your neighbour across the room in her undies wouldn’t give you a great pic

I went for the narrower boroscope and the 6 lights are excellent, those advertising more LEDs actually have a wider diameter.

Found some pics from straight out of the box

Thank you to all. I think this is worth a punt for £20. Cheers
