Excellent buy at this price point

I have had the bike for over 1.5 years now and can tell you that it’s a great buy at this price point. SRAM Nx group set is excellent with hassle free gear shifting and enough range to climb the steepest of climbs. Have done a couple of trail rides and the bikes feels reliable, especially with the Rockshox Judy fork.
