This product is fantastic value for the money. I've paid the same amount for heaters that had half the features this one does...heaters that broke fast because they didn't have the features this one has. I've used it for over a week now, and it keeps the water at temperature. I love the indicator light that says when it is one degree below and actively turned on to heat the water back to the exact degree. It's nearly impossible to find a heater at this price point with that kind of convenience and accuracy.

Good heater for a small tank or for a water dish outside! I use it outside in a gallon dish and it keeps the water thawed out even in below zero temps. The temp selection is good, super easy to work, built well and was a good deal for the price.

Nice little tank heater, but too big for a 1 gallon beta tank.

I am nesting awaiting the arrival of my new addiction Betta! ( I have had 2 in the past, ( lived 4 + years)All before Betta tanks!I had purchased a little lady a few Mos back, bought a 5 gal tank, plants, wood,etc. Cycled it, per all fish experts on U tube.Well.... got the lil girl.....floated her,She acclimated..... and Wella , she is home! She had the best of everything, or so I thought. I bought a heater to the specs of the tank. Thermometer says btwn. 72-76..ok, she is happy. Eating from my fingers, appearing happy.....then- noPlaying, no swimming, floating...I GO TO PET HER, she had succumbed to very cold water, HEATER FAILURE!! I'm devastated!(She even had a snail for a friend she hung out with).Well.... cleaned tank, cycled, etc. Researched heaters, found the Flugal noted it worked Great.Checked it every hour since I installed it, keeping great temp..78-80.Only problem, no suction cups came with it, but it is doing fine.I HIGHLY RECOMEND! Sorry for such a long review, but loss hurts!

Easy set up! I had a 60 watt generic wand heater in my 5 gallon and I thought maybe it was my thermometer getting a bad reading but that wasn’t the case! My lil man has been way more active and happy with this great heater.
