This worked fine with an on line and off line computer. Downloaded software worked good on an old vista as well as windows 10 computer. It did not work on my android phone. It proved I need to clean better.

Super easy to hook up to laptop and cell phone. Adapters are right there. Bore scope showed the interior of barrel great. Would show if any fouling or copper would be left behind. I am very happy with this purchase.

Works excellent, I really like this tool, it shows you why some barrels shoot better than others. You could spend a lot more to see as well in a barrel

Great product and cheap compared to others out there. The seller I purchased from also includes a little gift package makes it so much better would and have recommended this product.

Very nice little borescope - especially for the money. The attached images show a .223 barrel with the angled mirror adjusted two different depths, and without the angled mirror for a straight on view of the bore. So far I've only used it with a Windows notebook. I'm hoping it will also work with an iPad, using a lightning to USB adapter, but Apple is funny about how USB devices work on their mobile devices, so it might not.

It is very easy to use and shows the imperfections in the barrel of your rifle such as copper fouling. Works with any Windows machine(all I have tried it with. I recommend this product, I have now viewed all of the barrels of all my firearms. Something not quite right you can easily find an issue or rule it out.

Relatively easy to use once you sorta figure it out. Good quality images, and like that it came with a little free gift enclosed (roll pin punches and an AR sight tool) Shipped quick, and hassle free.

Only had it for a day, but used it to check out a .308 and .223, and it worked great. Good clear image, easy to use. I put it on my Chromebook and it loaded easily using the Chrome camera app.

Overall I find this borescope very good once in use. However, instructions for use with listed as compatible Linux OS are non-existant. With Android, I recommend you use the USB Camera app that is pictured in the instruction manual for ease of use. Unless you are extremely tech-savvy. I tried the other endoscope Camera apps, but could not figure out how to get them to work. The picture quality is excellent, and the adjustable brightness of the light is a great feature. This is a very useful…
