Anyone have experience with Hyskore Parallax Pistol Vise Shooting Rest?

I need to zero the sights on my Glock (standard Glock sights right now). A Ransom is out of my price range, but I'm wondering if I should get something a little bit better than a bag rest.

I guess no one has. I've never seen one in person.

Bump...

I need to sight in my Glock and I want something better than just a bean bag.

This doesn't seem too expensive.
