electronic chillers?
 

Hi,

I just found and bought a electronic chiller for $130 bucks. The brand is Yincheng. i was just wondering if anyone has used these before. i just have a small 40ltr tank.
I have only had it for 2 days, yesterday it was working fine, but today, its not chilling my tank at all. but it says its on. i am just wondering if they are just cheap and nasty and if they actually work.
