Works great
2 of 2 found this helpful I don't know how it can be this cheap but it works perfectly. The code is convenient to use and did arrive pretty soon. (Although it took a few hours for me rather than a few minutes but it doesn't really matter).
Amazing stuff.

Brilliant
Although it doesnt look so amazing but it is indeed an amazing mini transformer. Good for physics teaching demonstration.
