Anyone tried the Tweek Geek's Dark Matter Technologies Qubes?

I'm wondering if anyone has tried Tweek Geek's Dark Matter Technologies Qubes, and if so, if they'd be willing to share how they used them and what they heard.
I searched the net, but can't find any comments other than those on the Tweek Geek website...
Whoa! What? Another name infringement. 
I have tried the worm hole dot. Can't say it was a revelation but I only have the one piece and so many other tweaks.

Hi, ebm. What Tweek Geeks products have you tried?

Don't think Tweek Geeks would have found that particularly funny...
