I've been wanting a borescope for years and have borrowed a few Depstech models from friends. This Kentfaith blows the $50-60 Depstech away. The focal range on this is much better. I feel like the Depstech ones I've used can only see about an inch in front of the lense but this one sees as far as the light shines.

The light brightness is adjustable and there's a decent range of brightness settings. With lights on full power, the tip does run surprisingly hot. I'm interested to see if that becomes an issue.

The articulation is so cool. It does only articulate in one plane so you may need to rotate the cable itself to get the right view but it's still way better than no articulation. I found that the articulation lever was pretty difficult to move when the cable was wrapped up. In fact it would only move about 90° in either direction before I felt like I was going to break the lever. Once I unwrapped the cable, the lever moved much more freely and I could get the full 180° movement. The lever is pretty easy to operate even with one hand. At this price point, I do wish the articulation was in any direction.

The camera is very clear and has a good focal range for a variety of different usage situations. Taking pictures is super easy with a press of a button. My 6 year old son spent the afternoon checking out what was in all of our HVAC floor registers.

It comes in a nice case and includes all the cables, SD card and card reader for a laptop.

Overall I'm pretty pleased. There are cheaper articulating options out there, but Kentfaith seems to be well known and reviewed so you're paying a bit for reputation and quality I think.
