have a very old house and do a lot of DIY work around the house so I actually only have a few different endoscopes which comes in handy from time to time. I love the fact that I can see what's behind the wall or in a pipe without having to tear it down or open it up, which is obviously a much bigger task to patch. I was so impressed with the K&F Concept brand endoscope and when I saw this articulating model I just had to have it and in fact not only is it the best endoscope on the market it blew my mind and saved me a few thousand dollars preventive claims settlement. Please read on to find out how this amazing articulating endoscope has helped me save tons of money. FIRST IMPRESSION: It came in nice retail packaging and inside the box was a sturdy zipped storage case that housed this endoscope in a perfectly fitted shape for maximum protection. The device looks professional and solid in terms of material and feel, which does not surprise me given my previous experience with K&F Concept products. The 5 inch IPS LCD screen is very clear and the buttons are located just below the screen to change setting and mode. DESIGN, SPECS and FEATURES: What really impresses me about this endoscope is not only the swiveling camera head, but also the way the movement is controlled. They really nailed it by using the dial joystick control in the center of the grip so it can be easily controlled with your thumb while holding the grip. Any other design or button would have ruined the user experience, but they really studied and gave the best possible control. Right next to the dial joystick control are the camera button and light button. It takes pictures in photo mode or starts/stops recording videos with sound in video mode. The light button toggles between different preset levels of brightness or turns off the light. Simply brilliantly made and placed in the perfect spot. I also appreciate that this is IP67 rated so it can be submerged under water to inspect anything that contains water and also block out dust or sand. I was impressed with the built-in 3000mAh battery which can last for days if not weeks after a full charge. The beauty of this endoscope is that you can see everything clearly on the 5 inch LCD screen, so you don't need an app or phone to use it, and you can take pictures and videos and then play them back from the device, to view it from the 5 inch screen, not to mention 32GB memory card is included. What's cool is that it also has a WiFi function that allows you to stream what you see on the 5 inch LCD screen to another smartphone or tablet that has the free app installed, so another person can also see what you're seeing, which is really cool. HOW IT CAN BE MORE AMAZING: I really love this endoscope and while this is the best out there I wish these improvements which aren't a deal breaker for me but would only make it more amazing. 1) I wish the cable was longer. It is only 5 feet long, but other non-articulated endoscopes are about 15 feet long. There may be technical limitations to making it longer as it has a moving head, but 10ft would have been better. 2) It would be amazing if the cable could be detached from the device and then attached to the bottom of the handle (current design) or the top of the LCD screen. This design makes it easier to work with the rigid cable, depending on whether you are looking up or down with the endoscope. 3) It would be out of this world if they could make the next model with 360 degree articulation! HOW IT SAVED ME MONEY AND TROUBLES: We recently had a kitchen remodel and replaced all of our kitchen appliances including the range hood. The new range hood we bought was much shorter compared to our old range hood and we can see the opening under the new range hood for venting which we didn't see before on the old range hood. I decided to use this articulating endoscope to check what's behind the kitchen wall and noticed that there was a badly rotted wooden frame due to a water leak from the roof. We immediately hired a contractor to fix the leak, but the repair could have caused a lot of damage and expense if we hadn't known about it years later. I am very satisfied with this endoscope in many ways. CONCLUSION: Easy 10 out of 5 stars. I cannot say enough good things about this amazing device. It's so much better than those endoscopes with two or even three lenses because it's easier to just move the direction of the camera than trying to switch between different camera lenses. It's also much easier to slide and move the cable if you can guide the endoscope's head in the right direction. If you are in the endoscope market, look no further and get this one and it will be worth the investment. Recommend wholeheartedly!
