działa dobrze,jestem zadowolony

Excellent. As ordered. Very quick delivery.

Build quality is very good. Leads are plenty long for purpose. They make things super cool on one side and fairly hot on the otherside (always use a thick heatsink with fan on the HOT side) Cool side can have a smaller heatsink and maybe a small fan to ventilate the cool air from the freezing heatink around the chamber. Price is very nice and everything arrived in excellent condition. Packaging was very good (everything was safe)

I always found these interesting. Impractical but interesting. They are surprisingly resilient it terms of current and voltage. Didn't see what the relative resistance is on the page but the range of voltage and current makes it almost unnecessary. Not really sure what else to say.
