I have two of them. They are easy to use and are perfect for New Zealand long range conditions.
They have been in the 40c deg heat of summer and the snowy 5000ft tops in winter, and no problems at all. I fully expect them to last a lifetime of longrange hunting.
They are very reliable and precise with both windage and elevation adjustments out to 1500yrds.
The 4.5 to 14
and the 8.5 to 25
The features of these scopes easily enhance longrange capability, especially with the TMR reticle which both of mine have. I appreciate the finer crosshair.
