The memory, based on my other experiences with GeIL, seems to be very well made with solid performance. They even throw in a few nice things like the tin coated copper heat spreaders which will look very nice in any case, a nice acrylic case (doesn't do much but it sure is pretty), installation instructions for you newbies out there, and of course the lifetime warranty
Thermaltake's idea is not a unique one, but one we are seeing a lot more of in the market just recently. The unit's looks are nothing to write home about but will appeal to some looking for a simple blue aesthetic to go with there themed system. There are no flashy lights or LED's so if this is something you are looking for, look elsewhere; the unit is designed to be functional and simple above all else.
