Pros: Initially bought this because it is one of the few travel adapters I've seen that adapts to Chinese sockets. I was sent to China for a product promotion of my companies products. So for laptops, projectors and other toys that needed adapters, this filled the bill perfectly. The advantage of this unit is the ability to choose the specific adapter to the socket required. No big bulky multiple choice ones.

Cons: About the product none, the only down side for me has been that since all my colleagues have seen this item they all want one, or are hassling me for mine. So if you are in the need of a really simple to use adapter get this, but get two, because you'll soon have "friends" that want to borrow it.

Other Thoughts: The concept of the adapter is very simple, with it's swap-in swap-out. This covers the majority of the worlds sockets, but if it didn't the principle is simple enough that the manufacturer could offer other possibly "exotic" sockets what those maybe I can't think, but could be a useful way to expand a product line.

Bottomline: A very neat and convenient little package. Does the job required of it, well designed, easy to change between sockets, what more could you ask of it. For those that travel alot this option is simpler and smaller, and for the price why bother with anything else? Would I buy another, yeah. I'm actually about to order 5, see cons above.
