very good. The vortex razor line has better coating so comparison might be border tomato to potato but the customer service is great, and the image is amazing at long distance and full mag.
I flat out lost the eye piece on a scouting trip and vanguard set me a replacement for free. The focus dial has a fast focus and a fine focus, and there is a built in adjustable sunshade. I have gotten clean imagining on animals at over a mile away. Like most scopes, in low light settings is where the clarity starts to diminish. Going on a lower power setting helps however. For the price point it is great. If you are looking for exclusively shooting, I rarely look at bullet holes on paper through a spotting scope past 100y, but .223 holes are way easy to see, so I'll leave it at that. I've got some good vapor trails while digi scoping with this as well. The adjustable eye piece is nice to set eye relief and is rubber padded. Comes with a nice usable outside case.
Nit picking the mount that wraps around the scope, that attaches to the bipod came a little loose after about a year.. just took a screwdriver and tightened it back up...not really and issue.
