Served well for over 6 years, but eventually broke down
4 Stars
Served well for over 6 years, but eventually broke down
Bought 100 w for my 20 gal in December of 2016. It worked fine until today (April 2023). I guess it's hard to ask for something to work longer than that.Took one star off because it always bothered me that it's hard to read temperature setting numbers on the top and the actual water temperature never matched the number set on the heater.
Thank you for your feedback

5.0 out of 5 stars Still Good Almost Three Years Later
Reviewed in the United States on December 29, 2015
This heater has been great for my 29 gallon so far. It does a quick job of heating and I find it really doesn't have to run that long to get my tank to the proper temp. I love that it's not made of glass so I never have to worry about it shattering. I also like that it lets you know when it's heating and when it's idle. The included suction cups are by far the BEST suction cups I have ever used, you can't get them to let go for anything! I will update if anything negative happens, let's hope it doesn't! I've included a picture of it actively heating my tank.

UPDATE: Almost 3 years later this heater is still great, no issues whatsoever.
