    Order to delivery: 15 days. Pros: This is something to keep ready to use in a project. The good efficiency eliminating the need for head sinks. Cons: It is not expected to work with high impedance sources (small solar panels).

    Impression:Will be useful;

    Pros: small and reasonable simple. Cons: Worked only 2 minutes. I dobb.checked everything, but I seems to shortcircut the DC input and therefore does not deliver and output DC. I suspect the potmeter to be out of order, but have not yet checked it.

    Impression:seems ok, but does not work;
