This was the cheapest 3.5" enclosure I could find on the web. So what do you get for your thirteen quid? The unit I received was different to the one pictured, basically a simple aluminium box with plastic ends. And while it's not going to turn any heads down the LAN party, it doesn't look excessivlyl cheap and nasty. The "Copynow" button mentioned in Play's description is missing along with the promised support for external SATA daisychaining, but neither features are likely to be missed IMO.
Drive installation is perhaps slightly fiddly, but once I got the thing put together it was detected by Vista straight away. The lack of a cooling fan means it does get quite warm, so it's probably not best suited to 24/7 usage. Power and USB cables are included, along with a bonus comedy manual (which among other things, details "whopping the product proprly")
In conclusion, what we have here is a basic enclosure with the minimum of frills. If looking for a way to convert a spare SATA disk into some additional storage, why pay more? Those requiring lightning transfer speeds, constant operation, or grammatically correct instructions should probably look elsewhere.
