Review on Marina Nova Fahrenheit Only 86 Degree by Dawn Burg

I paid almost double the price for this item at Revain a week ago. When I put it on my tank, I waited a few hours and then tried to read it. The color for the temperature level is very difficult to read. I have to shine a flashlight on it to read anything because it looks completely black. When I could read something, there was no solid color. I waited a few more hours and checked again. There is no strong color yet. Then I thought maybe I should move the strip to a different part of the tank. I followed the instructions that said it could be moved and tried very carefully to remove it but it fell apart and was a mess. I am extremely disappointed. It was a waste of money.
