Ignore the previous reviewer, the description states clearly PS/2, not USB!
The keyboard itself is fine, in fact it's brilliant because it's a completely standard layout, unlike many others. Cherry make excellent keyboards and are much better quality than other cheap nasty ones.
The keys are standard size, the letters won't come off and the quality of the plastic used is better than average. Also, there are no keys that feel odd unlike some keyboards where the feel of some keys is completely different from others. This one gives the feel that it is well screwed together and will last forever. It's not flashy but it does a great job. Note that it's not a flat key or a super slim but it does have a relatively small footprint on the desk. Oh, and it has rubber feet so it doesn't slide around when you're typing.
If I have a slight criticism it's that the feel is slightly "dull" but this is not a major issue considering this is the cheapest decent quality keyboard you can buy!
Five stars for the price.
