I bought this for about 8,000 yen because I wanted to attach it to my smartphone and take telephoto shots. It was too heavy for me, and I'm too clumsy to use it well, so I'm putting it up for sale. It also comes with a mini tripod, so I think it's also great for using as a telescope. The telephoto function is perfect. Things 200 meters away look like they're right in front of you. I tried to use it once, but other than taking pictures this time, I haven't used it.
