Dxztoz Dual-Lens Articulating Borescope, Endoscope Camera With 0.33In Two-Way Articulated Snake Camera, 5'' Hd Split Screen,Waterproof Inspection Light For Automotive Engine Mechanics-5Ft

Great product

Great scope in every way. I bought a 2003 Suzuki Grand Vitara in over all good shape to use as little 4x4 for dual sport use. It has very reasonable miles on it. I discovered it was going thru a quart of oil every 200 miles with almost zero leaks. I thought I had been really screwed but hoped it was valve seals. I wanted to check the cylinder walls for excessive wear and scoring before doing anything. I looked at a lot of these scopes and settled on this one for a number of reasons. I liked the side camera. I found that this unit is so good it is not needed. These all have internal batteries which die over a period of years. This unit can be run off a USB-C phone charger or an emergency battery for recharging a phone. That means that as long as the electronics work, it is good to go. It comes in a very professional carrying case and special hooks and stuff to attach to the end of the camera. Excellent light brightness. Excellent video quality. Focal length is from around 3/4 inch to 100 ft or more. Over all picture quality is bright and crisp with great resolution. I could count the factory cross hatch marks on the cylinder walls. Flex Tip. Just over 180 degrees. I was able to look back at the bottoms of the valves. The flex function works very smoothly. The info I gained was worth the money I spent. I could see that I have no burnt valves, piston tops looked good with a thin layer of carbon from the oil and the cylinder walls are in new condition. I decided to try some AT-205 to see if it would soften the valve seals before having them replaced. If that worked, I know the rings are likely good. It did nothing for the first 300 miles. Suddenly after letting it set for a few days, and then starting to use it again, the oil on the dip stick seems to have almost completely stopped dropping. I calculate I am now up to at least 400 miles per quart if not a lot more. There is no more smoke at cold start up or after idling for 5 minutes and taking off in a hurry.

Work great. Very sharp pictures. I used it all the time in my small engine repair.

Purchased for husband to help with his work . Very satisfied with this product

I have two other borescopes. I've had both a while. One is a DeWalt and the other a Chinese cheapo. Both had limited focus range of about 6" to 2". This DXZtoz unit has incredible clarity both far and close. Then there's the articulation. A game changer for finding and getting a good view. One quick tip: I purchased two units; both the dual lens version and the standard. The dual lens is so much better. It has a larger screen. You can split the screen and look at both views side by side. With one button touch you can select full size of either view. I ended up sending back the standard version and exchanging it for a second dual view. Because of the specials being offered there was not a large cost differential. Either unit works well but having the larger screen is worth the extra cost.

Saved me from potentially more $ spend on an engine. I did not notice something dropped into the cylinder, and went to start it up. Heard pinging and immediately turned it off. Bought this as it was high reviewed and boom. Got the metal clip like thing that was in there out. it comes with a magnet adapter and made it super easy to get it out through the spark plug hole. Glad it wasn't too bad and now motor is fine. Would of been a bit harder to get out if I could not see it and was not sure it was the right cylinder to look into. Expensive but worth it to spend even more money on it. Would highly recommend. Image quality is good too. Its a bit hard to move the cable at first but then you get the hang of it.
