I use to have one. I picked it up locally for a good price (used) with the intent of having something to get a little closer look (vs my binos) without having to pack a big spotter (had a Theron Saker at the time). I wanted to use it free-handed, or leaning against something solid... but found out I didn't really gain anything over my binos when freehanded, so I ended up trying it on a tripod too. I also remember the field of view seeming pretty narrow, and the focus knob was kind of strange to manipulate while trying to keep things steady. Honestly... I wasn't too impressed with it and ended up selling it and getting a Nikon ED50 (which I would say is far superior). I've gone through countless spotters and binocs since then, but that little 10-20x40 Gold Ring was never missed. For what it's worth, I no longer own a little spotter -- I'll take 8x and 15x binos just about everywhere, and sometimes my big spotter.
