MS450-50FT

Like a lot of people, I bought one of those $30 endoscopes that require you to use an app on your phone to see the stream. Like a lot of people, I took an hour with it, threw in the towel, and shipped it back.This Teslong endoscope is the real deal. Yes, it's more expensive, but not prohibitively so and for that extra price you get a great picture, lighted dual-cameras (top and side), a sturdy, easy-to-use control unit, and generally good battery life.As soon as we broke it out, we went into the basement to thread it up through the floor to try to identify the source of a leak around the skirt of the tub in our 2nd bathroom. The multi-level light was up to the task of illuminating the darkened cavity and when we needed to sneak up around the side of the tub for a sides shot, the side camera performed well, helping us narrow down exactly where the leak was flowing.The one frustration I have, and it's not unique to this endoscope, is that the flex cable, while strong, still flexes a little too much when you are trying to aim a camera that is several feet away. Our solution was to find a piece of 1/4" PVC pipe that we had laying around, thread the camera up and in, tape the flex cable to the pipe to ensure it was not going to move when we twisted the pipe, and then use the pipe to rotate and aim the camera. This might not work in every situation, but it worked well for us.All in all, the Teslong "feels" like a piece of semi-pro gear, not like a piece of junk like the endoscopes in the $30 range. It's not a pro endoscope, and it lacks some of the resolution and other nice-to-have features of larger, handheld units, but it does the trick for the price.Highly recommended!

Works perfect for me. Auto technician and makes for a great tool for a great price!

The media could not be loaded. Update again in December 2024: The battery still doesn't hold a lot of charge but has improved since I tried it a month ago. It appeared that after a couple of cycles to using and recharging it, I can use it for longer each time. The video is the latest showing its charging status. The battery aside, this is a great endoscope in terms of the overall build quality, controls, and picture quality. Raised the rating back to 4 stars, with the understanding that some battery degradation is normal after 3 years.Update in 2023:I purchased it in 2021 and used it for a few times on cars and home projects. It worked nicely!However, now in 2023, I wanted to use it again. It was low on battery so I plugged in the USB-C charging cable and it didn't charge at all. I used different chargers/cables with the same result. You can see in the pictures the correct charging port was used and there is no sign it was charging. Couldn't seem to make it work now.I put it in the case and stored it in my toolbox/drawer when not in use. It was never abused. Very disappointed!=========== My original review in 2021 below ==============I've used it for car inspection and checking air ducts in the house. It works great! It comes with storage so you can take pictures and review them on the computer as well. The picture resolution is fine but a higher resolution will help especially when you need to zoom in on certain areas for details. Overall, this is a great tool!

I bought this endoscope to try to find the hole in my HVAC duct which was allowing mice into the vents (not into the actual house, thankfully; they were only inside the ductwork with the vent covers serving as a sort of "jail" which kept the mice sequestered to the ducts). The ductwork is in the crawlspace, but some of the runs are tucked up between the floor joists and hidden by underlayment...meaning I couldn't simply go into the crawlspace to look for holes.That's where this endoscope comes into play. I was able to feed the scope through the vent and down into the ductwork and did manage to find a hole (in addition to a bunch of junk). Since I was feeding it into a fairly large "pipe", it was a bit tricky keeping the scope oriented, as the semi-flexible cable may curve and twist as you feed it in. The more cable you feed in, the harder it is to control. Because of this, I think the 16 ft cable is the longest recommended length...anything longer will be too difficult to control in any space wider than a 2" pipe.I also highly recommend getting the dual lens camera. I found myself switching back and forth between the two cameras a lot. Often, the front camera didn't show much because it was lying directly against the bottom of the duct, but the side camera would show the top or side of the duct.The IPS screen is good quality and a nice size. Resulting video/pictures are good considering the size of the camera. I downloaded the pictures onto my computer and the quality actually looks a bit better on the endoscope screen vs my computer...perhaps because the pics are so much bigger on my computer. I've attached a couple pictures I took with this endoscope, both from inside the ductwork and also through a hole in my floor where a cable line runs (the previous owners of my house were lazy and drilled right through the floor instead of bringing the cable through the wall). This was my first attempt at using the endoscope and I'm sure my pictures will improve as I get better at holding the probe steady. I did find it difficult to figure out if I needed to push or pull to get the camera centered on what I wanted. Perhaps that will also get easier the more I use it.All-in-all, this is a handy little endoscope. In addition to household DIY, I could also see this being useful with car/engine repair. Who hasn't dropped a bolt or nut into a small opening when working on your car or lawnmower? The endoscope comes with a hook and a magnet which would help retrieve said bolt or nut. It also comes with a very nice carrying case.
