So looking at the reviews here it's really a hit or miss, I guess I got a bad one.
Going to return and see if the next one is better.
Got the new on in the mail, so far I tried it in the sink...the water temperature doesn't increase but it feels warmer than the older one, so I'll see how it goes. Also this one also created an oily layer, is this because I soaked it in water that's about 80 degrees?
I'm going to return this second one too. So after reading around about heaters it might be because I stay in a living room with really old windows so there is always a breeze so maybe that's why it's not working....so I guess I'll try the Zoo Med BettaTherm heater since people complain it runs hot...so maybe it'll be perfect for me.
