Great Budget Borescope For Inspections and Repairs
The borescope camera is outstanding. I inspect and repair RV's and this camera saved my rear end! I had a power cable get stuck way out reach in a ceiling cavity. The borescope helped me find the cord and I was able to slowly fish it out with other tools. Without this camera, the RV would have needed its ceiling dropped. The picture is adequate for the work I do. This is not a high end camera where you can remotely articulate the camera from side to side, but I don't believe I will need it because it has two camera views. I was able to take pictures and video to show the work I was doing for a customer. Very impressive. Zoom capability is modest with 1.5x but in cramped spaces, you don't need much more than that.

Great endoscope, very much worth the money!
Bought this for work because I was getting frustrated not being able to see what kind of blockages were in walls that prevented me from running cables. This thing definitely did the job. I was skeptical from looking at countless other models that were cheaper, or several other endoscopes that looked identical but were rebranded with other brand names. I decided to buy the bullet on this one, and I’m glad I did. Picture quality is excellent. It looks great, and gets the job done. I can actually make out what things are in the wall, which is even more helpful with the attached LED light at the end of the scope. Multiple brightness settings and quality settings make this a must buy for anyone who has trouble looking into tight/dark spaces. Recording on this device is also awesome. Being able to revisit past recordings is super handy, especially if you need to describe what you saw to others. The included memory card allows you to take plenty of pictures and videos as well. This product has been super helpful on the job, and saves tons of time and money. Well worth the price!

High Quality Industrial Endoscope
Very pleased with both the quality of construction and the quality of the images produced. As a serious DIYer I appreciate high quality tools. I put this endoscope in that category. During my 40+ years of experience I have learned it is typically worth the extra money to buy quality tools designed to do a specific job. Such tools typically operate with fewer problems, produce better results, are more durable, and are a pleasure to use, instead of being a source of frustration and regret one often has when buying inferior tools. I really like most everything about this unit. - The dual camera. Being able to see straight ahead and at 90 degrees, without having to use some sort of mirror attachment, is really helpful. And being able to switch between the two views without moving the probe is invaluable (obviously can’t do that if using a mirror attachment). - The semi-rigid cable. It is flexible, yet rigid, once bent to the desired shape. It retains its shape until you change it. It doesn’t flop around like many of the less expensive units do. - The high quality image produced by the camera and screen combination. The clarity is amazing and the details you can see is impressive. The images produced have been more than adequate for any inspection that I have done. - The adjustable lights built into the probe work well. They provide sufficient light for the camera to capture a clear image. In addition, being able to reduce the intensity of the light, at times, improves the image quality. The flashlight built into the hand-held unit is handy. - The simplicity and intuitiveness of the unit operation is welcomed. Since I don’t use the unit very often, being able to take it out of the case and immediately have it up and running providing images in a matter of minutes is great. Having a unit with more “bells and whistles” but one that I would have to refer to the instruction manual, to refresh my memory on how to use it, would be a real pain. Likewise, having to depend on establishing communication with a cell phone, and the inherent challenges that can come with the software on the cell phone recognizing and communicating with the camera, etc. is not a complication I need. - The case is very nice and appropriate for a professional/industrial piece of equipment such as this. Among other inspections performed, I was able to inspect my home’s HVAC ductwork to confirm the ducts were clean and free of any mold or mildew, saving hundreds of dollars by not hiring a specialty cleaning company to clean the ducts when they really didn’t need it. I cut diametrically opposed slits in a tennis ball and pushed the probe through the slits until the end of the probe was slightly protruding from the outside of one side of the ball. Then I was able to push the probe/tennis ball through the inside of the ductwork with the tennis ball keeping the probe about 1 ½ inch (i.e. radius of the tennis ball) off the surface of the ductwork. This technique worked well and allowed a thorough inspection to be performed.

Perfect for me!
Purchased this scope to hunt down a water leak in our motorhome. The first scope I Bought was a Harbor Freight scope. What a piece of junk. You get what you pay for. I searched amazon and decided to give it a try. Reviews showed people really liked it. FYI, after my own research I found out this manufacture actually makes medial scopes also. The scope showed up in two days. That very weekend I tried it out. The unit was fairly easy to figure out. the picture was amazing and all the functions worked as they should. I went to work looking for that elusive water leak. I will say while snaking it through it does get tricky to figure out the orientation. After speaking to my son who is physician assistant he told me it is all practice on knowing your distance and orientation. Well I found the leak in 30 minutes in the middle of the coach behind a support. I would absolutely recommend this scope!!! My only recommendation would be if you have a few extra bucks is to order the short scope accessory end for the unit. While the unit functions perfect with the long one the shorter one comes in handy for smaller jobs like automotive work.

Well worth it.
Works very well! I think the instructions were lacking a bit. But there were some great videos on here that helped me figure out how to work the product. The clarity of the images were great. Comes with 3 extra tips, a mirror, a hook and a magnet. Very simple to use. I did find the flashlight a little useless. But i highly recommend this product!

works great

I used in a few jobs and it saved me a lot of time and work. It needs some used to to adjust the direction and the focus. Sometimes you need to bend the camera cable to a certain shape before you inert it to make it easier to find what you are looking for but once you get the hang of it and you used the 2 cameras it is great .
