The while thing was under water, dry it out, still works though I think the light isn't as bright as before but it still shines good enough to see

I only used it once so far, but I was able to determine that my central air conditioner wasn't working because the A coil was icing up. I used an access hole about three feet away and around to see it.

I bought a similar endoscope a few years ago and found it virtually useless.
I need something that worked and found this one.
It works really well.

I bought this to look for an intermittent water drip coming down from inside the ceiling.

I just received the unit today and have not gotten to look for the leak yet, but I found another use for it already!

I have a corner kitchen cabinet with a carousel inside. Last week it got jammed in an open position. Something was jamming it with both the normal "˜outside' doors locked in a corner inside blocking it from moving more than an inch or so.

Soooo"¦ I powered up this endoscope and was able to slide it under the carousel and found a glass instantpot lid had somehow fallen off of the carousel.
Because I could now see the blockage I also found a way to get the lid out without having to take the carousel apart as I was expecting to do. The "˜scope showed me a spot where the doors were offset enough I could get a few fingers in and manipulate the lid enough to move the carousel enough to get enough of a grip on the kid enough to slide it out.

This scope saved me about an hours worth of work unloading the carousel, disassembling it, reassembling it and reloading it.

Funny issue in the process. I had just setup the scope and got it connected to my ipad and had images. About a minute into probing around under the carousel the image went totally orange! I checked all my connections, turned the unit off, rebooted the ipad - and STILL an all orange image.

I finally looked at the lens and there was a tiny glob of something orange (marmalade?) stuck on the lens! Cleaned it off with a paper towel scrap and had a better image, but it must have left a film. I dug out a wet eyeglass wipe and had a perfect image again. (I put a bunch if the lens wipes in the box with the scope now).

One really nice feature with this unit is that it has two lenses. The first one faces straight forward as expected. The second lens is at a right angle to the first one. So if you get in a tight spot and look around you can just switch to the second lens and rotate the scope. On other models you pull the scope out, screw in the 90 degree mirror and start over again. The dual lens unit was only about $15 more than the one lens unit.

Last note: I tried to get the hook accessory on the scope. But I had a very difficult time getting the guard ring off of the scope. It was so tight I need to use a leatherman plier with sharp teeth to gently, but firmly get the ring to move at all. One I got it to move I was able to use just my fingers to get it off and out the hook on.

Used this to do wing/engine inspections, some mandatory, in my RV8 experimental. First thing I noticed is that the side camera is most useful in getting into tight spaces and seeing side to side as you snake this camera into hidden areas. like the bore of an engine cylinder. Ease of use depends upon the phone you use. Light on tip and sides is important. Picture quality is excellent for inspecting for minute cracks in horizontal spare attach point. Like that my phone can display the image and store the picture.

Muy práctico es lo que necesitaba. gracias
