High quality and great value!
Works great, the articulating feature is a must have. Clear, bright screen and the storage case is nice feature too. The screen capture button is in a position that makes it easy to accidentally press; this is my only complaint.

High quality
This device is simply insanely good. The buttons are very intuitive and easy to use. Image freeze and photo capture work perfectly, and the camera head control is smooth and precise. It comes in a very solid, high-quality carrying case, which is great for storage and transport. Connection to the phone was fast and hassle-free — no pairing issues or glitches at all. The image and video quality are excellent. Overall, it feels like a well-built, professional device. Very satisfied with this purchase.

Solid tool for the price!
Great tool to have. Electrician of 9 years and Im always blindly fishing stuff down the walls. So it was about time. Picture quality is great. Kind of let down that I was sent a used (previously returned) one because it had a return label that was covered over by another sticker... even though I paid for a NEW one. Also missing the charger cable. But I hate going through the process to return and replace. The tool seems to be working fine.

THE BEST SCOPE I'VE EVER OWNED
Very nice Bore Scope for sure! I've owned several other brands, but so far this one is head and shoulders above the rest. If you've never owned / used a bore scope such as this, it's hard to understand the subtle differences and realize exactly why this Teslong is so great. I'll cover some points below that jumped out at me and which might help potential buyers better make their decision: 1. MENU SYSTEM - The menu system on this Teslong is very intuitive. That might not seem like a big deal, but until you have used some of the other scopes available on the market, it's hard to really appreciate how well thought out Teslong's menu and buttons are. I've owned a few Depstech scopes; and while they are very nice, as well, I find that some of their menu functions and buttons are confusing and less than intuitive in nature. This makes trying to figure out what you are doing time consuming and aggravating at times. Nothing against Depstech (they make a great product and I still use their scopes), but the Teslong menu system is just much, much easier to deal with on a daily basis while working. That makes using this scope a pure joy. 2. THE HANDLE - This is another thing which might not seem like a big deal at first glance, but it is. If you are attempting to video or photo something inside a motor, for example, being able to have firm control over the unit without covering up the screen and/or having to reposition your grip while the display is falling all over the place is quite a nice feature. The handle on the Teslong allows you to easily keep firm control of things and keep the unit stable while working, without requiring you to constantly adjust your grip on the edge of where your screen is (which is sometimes an annoyance while using other scopes that lack a handle). 3. SINGLE CAMERA - Wait what? What about those camera heads with 2 or 3 cameras? Yes, those are okay and they do afford multiple vantage points while working. However, in my experience, I have found that having to figure out the complex set of buttons to switch between camera A or A+B or Split screen with A and B or A and C or camera C and B is just a straight nightmare while working. The fact that this Teslong only has a single camera (which you can articulate) saves you from having to deal with all the overly complex controls required in order to jump through all the different cameras and combination of cameras on the end of the cable. So, single camera = easy peasy menu control. 4. THE ARTICULATING CENTER LEVER - This is one of the areas where this unit really outshines its competition. If you're shopping around on Amazon, you might run into similar units which have a knob on the left side of the handle (which is used to articulate the camera end). Here's the problem with that design: when you are holding those units, it often requires you to use your free hand to adjust the knob (especially if you need to operate the scope while in your left hand for some reason). With the Teslong, the lever is way easier to work w/ one hand by using your thumb. This, in turn, allows you to use your free hand to position and/or steady the cable as you probe into things like spark plug holes, etc. Having the ability to operate the scope with just one hand (either in your right or left hand) while precisely controlling the cable in the other is really a game changer and makes this unit super easy to deal with and flexible in all situations. Having that lever in the middle (verse the knob on the left side) really gives you a lot more flexibility when using the scope. You can control the position of the cable (and thus the camera) with your spare hand and then easily move the head back or forth to center your view using the lever w/ your thumb. NOTE: I'll include some snap shots of a 22RE Toyota motor I just used this device on and it was super easy to see if the pistons were oversized or not. The second photo attached to this review shows the camera head fully articulated and looking up and backwards at the intake and exhaust valves, after having threaded the camera into a spark plug hole on the motor. As you can see the images are quite clear. 5. RECORDS AUDIO ALSO - This unit has a mic which will allow you to record audio as well as video. Super duper handy. On units without this feature, you just have a video that is silent. With the Teslong, you can also record audio while working, which allows you to narrate what you are doing and what you are viewing in real time as part of the video. This comes in super handy if you need to review the video later at your desk and want to remember exactly what you were inspecting or looking at while working. This feature alone makes this camera really stand out in my mind. 6. STORAGE CASE - The storage case is very nicely thought out. It has plenty of room to store the cable. Not having to remove the cable is a nice bonus (with most units the cable just attaches to a USB port, which often times requires you to remove it prior to storage in a case). So all in all, I'm very impressed with this Teslong bore scope. This is the 3rd or 4th bore scope I've owned and it's by far the best and most enjoyable to use. The menu system is extremely easy to use and the one-handed operation is really a game changer in a lot of ways. I'm glad they offer a single camera version too, as this makes the menu even more straightforward to use; the ability to pivot around the head (back and forth from left to right) with just your thumb is more than enough to get the camera on target for the vast majority of jobs. This Teslong is easy to use, simple, down to business and gets the job done without interfering with what I'm doing or forcing me to navigate a bunch of complex buttons and menus. I absolutely love it. 5-stars for sure. Nice job Teslong!

Works Well With Surprising Clarity; Awkward to Handle
I needed something to inspect the inside of the carriage gearbox on my lathe. This worked surprisingly well with good clarity and depth of field, and the rotating head is EXTREMELY helpful. I had to go around gears and shafts to look at some areas, and found that by manipulating the rotating head you could go around them and even go through elbows on pipe, etc. The case is well built and should last a long time--cheaper plastic cases have hinges and latches snap off, etc. with little use. My gripes are: 1. The cable exits at the bottom of the unit, which makes it awkward to handle while manipulating it in the hole, etc. It would work better if it exited at the back, or even the top of the unit. 2. The cable is permanently attached to the screen. This makes it very cumbersome to charge as you have a 5 foot cable dangling from it when you try to set it down. 3. The battery charge indicator is VERY small, and you can't really tell how much charge is left. Overall it performed very well, and I would give a qualified recommendation based on the negatives I listed.

Solid value, high quality
Surprisingly high quality. High resolution camera and display, plenty of light, much better depth of field than I expected. Recommended.

Nice quality scope
Very handy tool, I purchased bc we had a water leak and I wanted to look behind our drywall to make sure no mold was growing. The cable length was long enough plus some! The cable camera was very flexible and was able to move it to get 360 degree view. The zoom quality of the camera was very good to get a close look, and the camera display on handheld was very clear, I was very pleased and it got the job done. This would also be a great tool if you were working on vehicles. The battery is charged by plugging in, and for the amount of time I used it, it didn’t even drain any of the battery. So I would guess you could use for quite a bit of time before having to recharge. The camera has a live view as well as it is able to take screenshots. Very nice quality and the price isn’t too bad either!

Awesome Borescope! Even better price!
This thing is absolutely outstanding for the price! I was able to use it to look inside the combustion chamber of an engine and diagnose a bent exhaust valve. When I repaired the valve and was reassembling the engine I used this to see inside the distributor bore to adjust the slot in the oil pump drive shaft so that I could get the distributor installed. I also used it to confirm top dead center on cylinder one as well. This was nothing less than a life saver. The screen is huge and the resolution is great. The articulable tip makes this thing so useful. You can even take a snapshot of what you’re looking at. I have seen much worse for much more money! If you need one just buy it!
