Review on OWC 0GB Mercury On-The-Go Pro: High-Speed USB 3.0/2.0 Portable Enclosure Kit by Jackquell Cash

Chassis works, but not for all drives without a power supply. The device should have an indication of how many watts are available to the drive. This case works well with the Samsung Evo 800 500GB but not the 1TB drive version which is why I bought it. OWC tech support was nice enough, but somehow defended their choice by not specifying the maximum available power for the drive. Some will just work, some won't.
