Consider if not using a controller By Starrme on 4/29/13

Starrme would recommend this product to a friend

Overall: Bought this as my first heater and have already replaced for my main tank. The digital display isn't a major benefit to me because I am using a controller. I will continue to use for heating my water change SW.

Pros:
- Lights up when heating
- Digital temp setting and display
- Read out is on outside of tank
- Has separate temp measurement probe

Cons:
- Makes a loud beeping noise when initially placed in cold water.
- Metal hooks to hold display too narrow for my sump rim
- Digital display is bulky
- Accurate to within 2 degrees

Note: If temp is significantly out of range, the heater will beep continuously. I thought my heater was broken when this first happened. The beeping is a warning mechanism for if the heater fails but is a major pain when using to heat up new ro/di water.
Easy Set Up Easy Read By Alexandria on 4/19/13

This was super easy to set up and I like the digital read out. No more squinting on the old timey thermometers. Got the JBJ Digital thermometer with this. They are about 2 degrees off from each other. However, the JBJ digital thermometer is reading the same as the old timey thermometer so I trust the new digital thermometer and will set the heater 2 degrees up or down as needed.

Also impressed by how small it is. So in a small tank it's not this big honking thing that's getting in the way. If you have a small area for your heater this would be the way to go.

Will update as we go to see if there are any problems.

Bought two of these, one is still working flawlessly. Plugged in the second one the other day and it made an awful hissing sound like some sort of gas was escaping through the rubber ends and I noticed a weird smell. Not sure what happened, contacted finnex to see what they can do.
Great for the price By Travis on 4/1/13

There seems to be a 2 degree difference between the thermostat and a separate external thermometer I use, but that is easy enough to adjust for. My only other complaint is having to reattach the suction cups to the wall every few weeks. With any sort of flow, they seem to lose their hold.
So far so good By Mascis on 3/30/13

I don't have a controller, so these make it easy to check my temp on an ongoing basis. It's not glass, so there's no worry of explosions. And a small alarm sounds at a drastic temp change. like when the probe came out of the tank accidentally one day.

I have a couple of the larger units in my 57 gallon reef, and they do great at maintaining temperature. Unfortunately, after trying 2 different units, the small 50W unit is not large enough to maintain temperature in my nano tank. It will only raise the temperature by about 4 degrees in a 12 gallon tank.
The Best By Ryan on 3/21/13

This is by far the best heater I have purchased. I have had expensive heaters and cheap heaters, but this heater does it for me. It's easy to operate, the built in alarm for temps too high or too low is a life saver (literally for your fish) and it's not glass so I don't have to worry about it breaking in my tank or sump. I have one in each of my fish tanks and have gotten a few friends to buy them too!
Great Heaters By Gary on 3/19/13

I have both a 150w and 100w. Both have been working great for 6 months now. I have been using a temp probe and they are as accurate as the claim. The built in remote temp sensor cord could be longer.
Love the digital control By Ray on 3/15/13

I have this in my 29 BioCube and it works great. I love the easy to read digital control. It's easy to tell if the heater is on or off and what temp the tank is at. I'm going to get another one for my water changes.

I haven't used mine yet, but beats the glass heaters.
