I have one of these, and I like it -I would recommend for backpacking or some other lightweight, basic use where you aren't expecting amazing magnification.
I bought mine for backpacking trips - where I wanted a little magnification but didn't want to carry much weight. I think it served pretty well for those purposes. However, I should note that it is water-resistant, but not water-proof. I still have mine, but the optics have never been quite the same since I took a swim in the Yellowstone river, and forgot that I had it in my pocket. Since, I picked up another monocular with a little more magnification, but my new one weighs just a little more as well.
