I haven't noticed temperature making any noticeable difference.
Lighting conditions can make it play up a bit in very bright or dull conditions, but I've verified against my 338 Lapua Improved out past a mile and with my other rifles at long range and have been impressed with it for what it cost.
(I didn't buy it in NZ and it was a lot cheaper than they are here).
How accurate have you found yours to be after it warms up?
