Amvona rail system

Does anyone have any experience with the Amvona rail system which is being sold on Ebay? I am a hobbiest with a small studio in my home, so really heavy duty equipment isn't required. I just want something functional that will last under light use. I'll be using speedotron brownline strobes. Any other options or opinions would be much appreciated.

I have one of their products--a lateral tripod arm with mounts for four heads. It was cheap, and their service was good, but it's built a little light. It's fine for 35mm and other small cameras, but I'd use it more if it were sturdier.
