Sunyiny First Impressions

Overall happy.

This is a powerful heater that holds temperature very well. The temperature difference was very minor. Or better yet, conceal it to the back corner. Product was received fast, works excellent! Checked the accuracy of the heater with an infrared thermometer. I left seller feedback yesterday but have yet to hear from the seller. The controller is easy to use, very accurate and reliable.

Sunyiny Final Thoughts

I'll see with these.

Well worth the money the first one I bought still works great. Maintains it well except when the weather is already warm then it over heats it. I tested it by unplugging and replugging it. I have it set to 81F to get a 77F water temp. This heater is NOT fully submersible. Sometimes you may have to tinker around with the dial. The heater is super thin and the reflective surface is interesting.
