I bought this to inspect my HVAC ductwork and coils contained in a unit in the attic. This thing was awesome. I do need my ducts cleaned but my coils are in great shape. It came with more cable than I will probably ever need but I see many other uses for it around the house.

This is amazingly good after being totally disappointed with the Harbr Freit version for looking inside walls. The 8mm tip slips easily through a 3/8 hole, and with its rim screwed off can just fit in a 1/4" hole. I can make a view hole outside a switch box but will still be covered by the wall plate. I got the dual-lens, and the side view lens is the most useful one inside a wall. Even with no focus or autofocus, I can see well enough from close up to at least 2 feet. The LED is plenty bright and can be dimmed for close work. One weird quirk is that the image is 90 degrees rotated from the tip, which makes it very hard at first to tell right from left, and which inside of the wall is closer to you vs farther away, and it's not intuitive which way to turn the scope while viewing. The Rotate button will flip the image 180 degrees, but not 90 degrees.This solves stud finder problems and more. I have mortar on perf-board walls (like plaster & lath), and all my stud finders fail miserably, including the wall robot Plus that attaches to a phone. Miserably. But this scope shows me approximately where the studs are, and discovered how deep the stud space is, and showed me a 2" pipe next to a half-inch pipe, and how many electric wires, where they are, and whether they are stapled to studs; so I can avoid drilling or opening the wall in the wrong place.

Like the camera overall, little difficult to handle until you get used to it, but does its job

I only used it once to try and find the clog in a tub drain. Worked fine and seems like all components are of excellent quality.

Very happy. Excellent instrument.

Bought this for automotive work. When put up against a Snap-On scope that costs 5 times more, this scope has a better and much more clear picture. For the price, you can't really get any better.

It’s got good picture

This camera blows those cheap cameras out of the water. I love the clarity of the camera and the secondary side camera is so useful for those side views. I highly recommend this product.

This product is amazing. We purchased it for use at the volunteer fire department my husband is with. Very easy to use and provides great picture quality as to what they are seeing in the walls or wherever they need.

fácil de operar y de muy buena calidad
