I have the .20 Rigid version and it just enabled mt to diagnose a severe lead spitting problem on a customers S&W 617 Revolver. I used it without the mirror attachment to examine and record a video as a cycled it thru all cylinders. One chamber was WAY out of time and another was almost as bad. I had previously pulled the barrel to set it back a turn and cut a new forcing cone in an attempt to cure the problem without success. I had checked the timing with a range rod and that using this method the timing seemed OK. The forcing cone from the factory was the worst I have ever seen….it resembled a counter sink with no discernable taper at all. I cut the new cone to minimum depth as measured with my Brownells gage and it helped a bit on the leading. I ordered the borescope and it showed me what the real cause was. I tweaked the hand a bit and peaned the two offending cylinders lugs on the cylinder star a bit and deepened the forcing cone to just shy of the max step on the gage and now no spitting at all and a very good improvement in accuracy as well. As far as I am concerned this borescope just paid for itself. At the going price this belongs on any serious shooters bench.

Hey, A quick fix for loose ends on anything. I very light dab of silicone on the threads will act as a shake proof. Very very little will take up the slack and still let you turn the nut, bolt, mirror end or what ever.

I had mine the original one.
Yesterday, I lost the mirror. Teslong promised to send me replacement.

Another issue, is the software. The best Teslong can do is to provide a good software. The ad-wares that are available on the Google play, are horrible with their ads.

I have the original Teslong and Lyman rigid borescopes. Both serve the purpose. Hopefully Teslong will provide a wifi rigid model next. I will upgrade if they do.

Great review. Answered many of my questions regarding the related devices required to make the unit function. As an old fellow hopefully my grandkids will be able to help me make it work.
