onOne Software users?

I just stumbled upon some software that I've not seen before. It consists of plugins that work with Photoshop and Lightroom and Aperture. http://www.ononesoftware.com/products/

They have a couple that are of interest to me, such as a Layers and masking plugin for Lightroom. I'd like to know if the company is a good one and has good products. So, I'd like to hear from any users about their experiences, pro and con.

thanks
