"I bought the 7."

It is a bonus that the heater is titanium. I use a 50 for a 5 gal and a 10 gal tank. Sometimes it gets outside of it's ability to cool but only within a few degrees. I contacted the manufacturer and they sent me a new unit in less than a week! But my guys don't read them and don't listen! It took about an hour to reach 80f, which is fairly quick. I used to try those other cheap heaters sold on amazon.

"I like the size."

Once I opened the box i noticed the quality of the construction. The red light means it's off, blue light means the temperature is constant. My fish likes to get close to it and he has never been hurt by it. My fish likes to get close to it and he has never been hurt by it. They shipped us the upgraded version that also heats!

"Works great."

This is a great heater that is very easy to set up and program. Beware, but we are hoping for a good outcome! Also I like how it shows both the current temperature and the set temperature. I recieved this product without the instructions or the added thermometer. Temperature is slightly off by running a little warmer. This little heater is perfect; this is our third purchase of the same heater. The line is there due to regulations in certain countries.

"Quality was amazing."

It would stick out of my 30 g wide tank if I were to put it vertical. Well worth the money the first one I bought still works great. We received the chiller promptly and put it into use. But I am single and don't have to worry about this. Or better yet, conceal it to the back corner. If the water runs low or air gets in the heater shuts off. I'm in the process of setting up for tanks.

We would consider a replacement and then we would return the defective unit. I tested it by unplugging and replugging it. I'm not a big fan of the big glass tubes. I emailed the email it says to and told them. They promptly fixed the issue without any delays or drama. Per my thermometers, they are all staying constant. This product came in the nick of time!
