I have a V10x38 as well that I have owned for about 20 years. Extremely reliable and has probably sat on at least 10 rifles. I do notice that an adjustment sometimes seems to take a couple of shots to settle in but once sighted in it seems to maintain zero. I wouldn't want to dial it though based on this.
I also have a KT15 on a Win HV that seems to work well and is pretty bright. It has not seen heavy use though.
I like them ok but will generally save a few more bucks and buy the Leupold anymore.
