I have it. Pretty damn impressive after tinkering with the focus and the lighting. Each caliber will need different 'settings' i did .223 6.5 and .308 so far.
I bought it to check for pitting and mostly to see gas block port alignment. The angle of the light doesnt really reach down into the gas port but its just enough to confirm its aligned. It focuses no problem but its dark.
Major con is just like a lot of decent chinese sensor electronics it runs off of a buggy app. In fact i blame the app for completely bricking my galaxy s9. It happened the same night few hours after installing. Id post the pretty clear shots i got of the 3 barrels i used it on before it crashed but all my photos not saved to sd card are gone for now
. Im afraid of downloading the app to my only working smartphone i have left. I may try it again after black friday, if i find a good deal. Otherwise gonna wait til galaxy 11 in feb. I dont want to download to my tablet or pc. Before the black screen of death the app would get blocky n freeze after about 1-2 minutes of borescope use.
Anybody bought one?
Tell me how you like it...............
