Amazon Customer 4 Overall I am pretty happy with the scope. There are a lot of similar products on amazon right now and it’s tough to know which ones are good and which ones are junk. When I turned it on and connected it, I was pretty impressed by the quality of the pictures. My only complaint is that I wish it had an adjustable focal length. After using it in a few different situations I felt like it would be nice to be able to clearly see things that were much closer to the camera than 5-10cm. The fixed focal length isn’t bad, but the ability to adjust would make it significantly better. I like that this model has a rechargeable battery. The attachments are nice except for the mirror. They screw on quite securely. The 90 degree mirror is barely functional, but that wasn’t particularly important to me. Overall, I would recommend that people who are looking for an inexpensive, general-purpose boroscope consider this one.
