I had a chance to evaluate my brother-in-law's Swaro range finder last night and I agree it's slow.
The optics are great, just what you'd expect from Swarovski. However, I felt the unit needed to be a bit larger to use with both hands or a bit smaller for one hand use, it was kinda awkward for me to use and obtain a steady site picture. It just didn't feel good in my hands....but that may just be me.
I had issues with the activation button. The button on this particular unit seemed very stubborn, you had to press it in just the right spot or it would not respond. This would really concern me during cold weather hunting while using gloves.
I couldn't get enough eye relief either. The eyecup would not extend far enough for me to keep my eyelashes from touching the ocular lense. I could have held it farther away from my eye, but I like a good eye to eyecup weld, it helps me steady the rangefinder at longer distances.
We ranged several objects: utility poles, fence posts, deer feeders, grave markers, trees and houses. We could never get the same yardage on the same object. Could've just been us, but we had variations up to 21 yds. apart while ranging the same object.
Don't get me wrong, I'm not trying to pick the Swaro to pieces, but I would definately hold one in my hands prior to plunking down that kind of money. The Swaro just wasn't for me (and I love their optics). As far as range finders go, I'll stick with the Leica or Bushnell Elite.
