I mentioned in an earlier post that I ordered some of these to check out and they came in yesterday.
Summary:
Shipping time was on the good side and the products are great. I only ran through the pixel and dome lights, so that is all I'll post on now.
Blip:
Ben at the site is very responsive .. with good information 
Shipping:
They were shipped quickly and once out, made it to Florida, USA in a week, (I was happy with that shipping time, I order from China alot).
LED Pixels:
Was able to pretty much plug and play the 5v 8mm and 20mm pixels using the code in the sites project pages. The mechanism is the same to run both lights, minus the RGB order which is easy to abstract. The application logic is simple and easy to use. Was able to update the application very quickly to do other stuff like fade up colors and cycle a rainbow across the strip. Adding this into my existing apps should be a snap (just update where the rgb writes to .. update happens as usual in the background).
LED Dome:
The 12v, 50mm domes are really nice looking and setup in a snap with a 12v power source. Was able to control them with the arduino pins no problem.
Diffusion:
The diffusion on the 8mm LED pixels and the dome are perfect. I'll have to play with the 20mm's more to give a final on those.
The 5mm diffused RGBs from e-bay still needed further diffusion to actually work - these do not. This is major for me, so I figured I pass that along.
When I get the strip and other stuff working, I'll post more along with videos, etc. Just wanted to post details from last night before my day starts.
