Rated 5 out of 5 by from Great product Have only had it a couple weeks and have used it, only a couple times. Easy to use. Let's me see inside walls to avoid cutting anything that I should not cut. Listed durability as 3, only because my short time of ownership, and limited use, so far, make it so I can not attest to durability. That said, it feels substantial, and I expect that it will live up to my expectation, since all of my Ridgid tools do. Why would this one be different? CC

Rated 5 out of 5 by from Brillant tool to have when you need it. Having to look at a problem with an inbuilt toilet cistern, I would have never been able to solve it without dismantling it, had it not been for the Ridgid inspection camera. The screen image is a perfectly clear one, plus with the adjustable LED lights around the lens I was able to see and locate the problem and rectify it. One of my best buys.

Rated 5 out of 5 by from Built in screen / lighted with control amount of light this united is great for small areas. could stand to have a little long reach. other then that the color screen is Ideal and the lighted tip with adj. light density makes sharp images. and the adaptive attachments for retrieving stuff is good

Rated 5 out of 5 by from Helped me rescue our hamster Our daughter’s hamster (Samster) had escaped from her cage and somehow had found a way to get into the floor of her second floor bathroom. I bought this to try to see into the cabinet. Eventually, we heard her running around the kitchen ceiling and took out a can light to look around and there she was! It was really easy for a non-professional to use and had a great picture and lots of light to see.

Rated 5 out of 5 by from Just what I needed. Daughter accidentally dropped a class ring with sentimental value into a hard to reach duct under a bathroom cabinet. Was able to see the ring and use the hook attachment to retrieve the ring. Cost of the unit was less than the replacement cost of the ring, and less than the cost of tearing out and replacing the cabinet. And my daughter's happiness: priceless. I'm sure I will find other uses for this unit.

Rated 5 out of 5 by from Very helpful We needed to inspect a drain pipe that was inside a wall that had a leak, We wanted to know where the leak was before cutting large holes in the wall, This allowed us to cut a small hole to insert the camera head and find the leak before we cut the hole to fix it, saved a lot of time and trouble. I am sure we will find many other opportunities to use this device.

Rated 5 out of 5 by from Good product for a decent price, can't beat the lifetime warranty Bought this to look at a pipe in the wall on a job I was doing. Figure I wouldn't be using it much but it would be nice when I do need it. Was I wrong, I've only purchased it about 3 weeks ago, I've used it to help me trace a vacuum line on one of my trucks, I've used it to inspect behind the wall in a vent relocation side job I'm soon going to do. At $100 it's not a cheap tool, but it is one of the cheaper models out there and luckily Ridgid has a lifetime warrantya lifetime warranty that helped seal the deal between this and the other brands. This is my first Ridgid purchase I have not been paid nor offered to test products for Ridgid, but I wouldn't mind that at all.

Rated 5 out of 5 by from Excellent Borescope at a Reasonable Price This is an excellent product that is easy to use and provides sufficient resolution. This borescope enabled me to find a small leak in the transom (stern) of my boat that even the authorized manufacturer service team could not find. My only criticism, an extremely minor one, is that the image on the display cannot be viewed at any appreciable angle. Rather it must be viewed by the user looking straight at the monitor. However, this is a minor concern since the optic tubing is sufficiently flexible to permit tilting the monitor for optimum viewing. I should add that the battery life of the four (4) required AA cells is excellent. So far, I have used this borescope continuously for approximately three (3) hours and the batteries are still good. In short, this is an excellent piece of equipment at a very reasonable price.

Rated 3 out of 5 by from Not for outdoor usage You need to use the tool at somewhere has almost no light. Otherwise you don't see the screen. Even if you want to use TV out, you have VCD quality, which doesn't satisfy... So, if you just want to see what is inside of whatever you are inspecting you can go with this tool, if you need high quality images and want to use it at outdoor look for something else.

Rated 5 out of 5 by from It works Very useful tool for DIY. A little difficult to use initially. Viewing screen very crisp but you can't view it from a side angle. The 4 foot cable is just about perfect for home/DIY use.

Rated 3 out of 5 by from Didn't work when I needed it Bought this inspection camera thinking one day I would need it for a task. Checked it out when I got it and it looked like it worked but did not uncoil the cable...big mistake as it turned out. Had a plumbing problem and needed to look into a wall and down a pipe, pulled this camera out of the box and when I uncoiled the cable the picture screen went fuzzy and then blacked out. Fiddling with the cable would bring the picture back for a few seconds but not consistently so essentially useless. RIDGID replaced it for free with a new one under warranty but I had to pay $22 to ship it back to them which seemed unfair to me. Tested the new one out and looks OK, lesson learned.

Rated 5 out of 5 by from This Ridgid product was the best features of the four manufactures I reviewed to purchase. It was easy to use and the light brightness was excellant. The view screen was good size. Only wish I had was for a longer probe, maybe 5 or 6 feet.

Rated 3 out of 5 by from Good Value , adaquete. Does the job indoors. Great flexible probe. However screen brightness is compromised when using outdoors in the sun , for instance on a boat deck. Good value for the price which is why i bought this. However, if you desire connectivity features tablets and cell phones, this is no the one for you. Has an RCA jack, but that's obsolete.

Rated 5 out of 5 by from Very clear and easy to view the camera. Used this inspection camera viewing inside the RV water heater for build up, finding an object that fell behind the kitchen stove. It is great for any space that needs to be viewed that would be impossible otherwise, the light is also great for those dark areas. I would recommend this camera to anyone that needs to see in those areas great quality.

Rated 4 out of 5 by from Good value This device paid for itself in one project. Wish the "camera" was smaller but otherwise very happy.

Rated 5 out of 5 by from For the price, this is really a nice unit. Needed something to see under the porch on my house, Did an excellent job, image quality was very good. I liked the ability to increase the lighting as needed along with the ability to rotate the image if needed. I'm sure there are better, but for the price, it seems to be a well made thought out unit with a nice hard case to boot.

Rated 3 out of 5 by from nice performance great picture but easily broken love this tool but when I went to change the batteries I found the battery pack contacts broken on the tool side. This internal damage should not happen I would expect this from Harbor Freight tools, But not Rigid

Rated 5 out of 5 by from work great I bought the CA-25 to locate a water line behind the wall, drill a small hole for the camera and was able to locate the direction of the water line work great with no problem

Rated 5 out of 5 by from I’d buy it again Good price, easy to use, works great. I wasn’t sure about the purchase but I would definitely recommend it and I would certainly buy it again.

Rated 5 out of 5 by from Product works well The only drawback is the OD of the camera. You have to have a .75 inch hole to get it through. It would be great if it was a little smaller OD

Rated 5 out of 5 by from save your neck only have used CA-25 a couple weeks but has already saved me time with repairs and able to read serial & model numbers needed for repair parts. Don't have to move anything to get access or see around corners. Save on bending neck to look up at floor & ceiling joists for plumbing.I know there are better cameras on market but works great for my needs

Rated 5 out of 5 by from Great for in-wall inspections! I have some low voltage wiring to do and needed to look in the walls to see where would be the best place for it. This worked great with a great picture and adjustable lighting. I'm sure I'll find many uses for it in the future...
