25W 50W 100W 200W 300W Aquarium Heater, Submersible Glass Heater for 10L-300Litres Fish and Turtle Tank (100W for 40-100L)

Great heaters, cost hardly anything and just work. The dial to set the temperature I see as more of a guide and always use a trusted thermometer to get an accurate temperate over the tank, then adjust accordingly. Little indicator light to tell you when it's on and off and maintains the temperature reliably.I just wish a company would make a heater that blends in a bit better!

Great little heater but sadly too big for a 15l tank plus it doesn't have a temperature display

My 50w heater couldn’t keep my 55l aquarium at anything more than 23° during the recent winter freeze when our indoor temperatures were about 16-17°.I didn’t want to risk putting a 100w heater in as I experienced a wipe-out some years ago when a thermostat failed on a heater that was too big for the aquarium it was in and it killed all my fish.I was pleased to find this 75w model and it has worked a treat. The heater I received was a Hitop.The weather was still cold when I received it and it did the job perfectly. So far I’m very pleased.

Heater works great

Ok

Perfect size and fast heating feature make this product more appealing. Price was very affordable. Highly recommend this for small to medium sized aquariums.

This is a nice little heater but the temperature gauge seems to be off, when i used this for the first time i had a digital thermometer in my grow out tank, I set the heater to the temp i required and kept a eye on the gauge it started going past with no intentions of stopping so i had to keep bringing it down until i got it to where i needed it to be. when i got it to the right temp i have no longer needed to play with it and it keeps the temperture within range

Easy to install. Very easy to adjust the temperate and also to see what temperature it is sat at. The additional temp gauge sticker for the tank is great and my tank's water temperature has been consistent since installation
