I bought an HS-T 4-16x oh... sometime after Christmas, so a few months ago and am very pleased with it. Previously I bought a PST for another rifle, which I still have but always begrudged paying the extra cost for the illuminated feature that I never use (on the reticle). Typically I chose MOA turrets and reticle. At such an affordable price, the scope boasts many useful features: Easy to read dials with very audible/noticeable click adjustment and visible from prone or off the bench with little movement. Glass is surprisingly clear at least in the model I purchased - Not as brilliant as that on my Zeiss, but I'm not trying to shoot rolls of electrical tape in the dark.
As to durability: I liken it unto being a Viper PST without the illuminated reticles. Mine is serving (without issue) on a 222 rem which weighs almost twelve pounds and I've only had it for a few months, but given the Vortex warranty and Viper reviews I expect little trouble even if subjected to heavy recoil... but, this review is still based on my circumstances.
If you ask some more pointed questions, I can try to answer them.
