Been using mine since the middle of last year as it came on a gun i purchased.
Took a while to get used to as i went from an MTC Connect with zero eye relief to the sightron with loads.
Its taken a while but i am really happy with it. Great colour and crispness, minimal PX issues and good depth of field.
Totally agree about non locking turrets. Using an Aim Sports Range Bag the handles catch on the turrets and have turned the windage one a few times.Tried tape but didn't like it. Have them set to Zero so i can see where they should be and reset if moved.
Lenses don't seem to fog if you breathe on them in the cold which is a big advantage, and the ret is not obtrusive, although i have struggled to find it on targets in low light and shadows.

If they put a locking system on the turrets, an illuminated ret and made it the same price here as in the US it would sell like hot cakes.
As it is i have no thoughts of changing it unless the new MTC Connect SL is as good as i hope it to be.

Cheers
Alex
