Pros:
Very cheap, do what it should, and easy to modify for your needs.
Cons:
Could have been better documented. Does not come in any form of antistatic packaging. Short leads, but you probably want to solder directyly to the board anyway.
Other:
If you are running it on DC, remove the diode bridge (4 diodes) I tested it with several powerLED's bought from different sources, it works fine, but really, why shouldn't it ? :)
Bottomline:
This product is cheaper to buy just an inductor to build the device yourself.. at least here in Sweden. Very easy to modify for your needs, if you download the datasheet for PT4511 it's more or less built the same way as their typical application, so very easy to convert to 3W-version or make a dimmable version.
