It’s not as good as a $5000 NV scope, but for the price it’s excellent. I would absolutely recommend this to others and would buy it again. That doesn’t mean it can’t be improved however. The battery low indicator is all over the board: saying low battery even when fresh, giving inconsistent readings from one minute to the next, etc. And it is a battery hog. Buy rechargeables and have a fresh set ready. I’d also give the top buttons a different tactile feel to help distinguish them in the dark. As for the app, make sure you connect to the WiFi in Settings BEFORE you start the app. But the bottom line is: this is a great reasonably priced NV scope, and I’m very glad to have it.
