Marina 11233 First Impressions

The accuracy is perfect.

This product came in the nick of time! I got this heater for my 55 gallon aquarium. They promptly fixed the issue without any delays or drama. When i installed them, i let them sit in the tanks without power for 6-24 hours. I adjusted the set temperature a little lower to be more in the range I wanted. Those turned out to be a hit and miss. I think it works well to not stand out like other heaters.

Marina 11233 Final Thoughts

I like it.

The temperatures are pretty accurate. Product was received fast, works excellent! The temperature lights up so it's very easy to read. The temperature gauge is fairly accurate in my 55 gallon tank. The bonus digital thermometer it came with has been super helpful, and is accurate. The temperature gauge is fairly accurate in my 55 gallon tank.
