hygger Small Aquarium Heater, 50W Submersible Betta Fish Tank Heater with Digital Display External Controller, Turtle Tank Heater Suitable for Freshwater up to 45L Tanks

This is a very handy heater that is more than capable to heat my 80 litre fish tank. It's nice and small and with the added benefit of the digital temperature readout makes it easy to use. After around 5 months of using the product, the heater did stop working and this was noticed via the digital temperature readout that the temperature of the fish tank was starting to drop. I contacted the hygger support team, went through some simple troubleshooting to find that the device stopped working. They sent a replacement within a couple of days of confirming which is great to see. Overall happy with the product and the service provided by the support team as well.

It’s compact but it really does a good job at keeping the tank at the correct temperature.

Fully failed after 30 days and did not heat my 30 ltr betta tank. My fish was at risk and luckily for me, amazon online support were amazing and refunded me fully even though the chat bot would not let me return it. I was able to order a trusted brand name beginning with F straight away and fit that the next day. Not sure if I had a one off faulty one and the actual heater looked amazing and had a handy temp gauge which alerted me to the problem but I can't take that risk so it's a big no for me. Such a shame.

Use this on my smaller 55 ltr tank and it does the job fine. Its discrete and blends in perfect. Wouldn’t use for anything larger though especially if room temperature is an issue.

A compact unit made from metal, it seems well constructed and didn't take long to get to and maintain my desired temperature. Easy to adjust, the lead to the control unit is ample, the same goes for the lead from the control unit to the heater.

Needed a heater, actually I needed a 100w heater for a 90 liter tank we were setting up but the 100w one was needed in the first tank.So bought this one to fine tune the temp while setting up.OK, it did take a day to bring it up from to temp and once it did, kept it just fine.So for a smaller tank perfect but will work hard as a emergency spare heater.

Had an issue with the first one but the seller has been amazing and issued a replacement. I really appreciate the support they provided as it was during the heatwave in the UK so I wasn’t 100% whether it worked or not…It’s perfectly silent, great quality, keeps the water warm, I have it at the bottom side of a 25L tank, the temp ranges quite a bit so super useful, and does its job well, maintaining the temp.Easy to set up but the grips were a little hard to put on

This compact little heater is perfect for my small 45litre (10 gallon) tank. The black disappears against the black background of the tank. The digital readout is accurate against a thermometer in the tank.As with other Hygger products, well designed and well made.
