## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Works for me
  

*by B***I on Reviewed in the United Kingdom 🇬🇧 on 25 November 2018*

25 litre tanks. Keeps the temperature where it needs to be for Beta fish. No problems with it thus far.

    Hot Stuff
  

*by R***H on Reviewed in the United Kingdom 🇬🇧 on 2 June 2013*

This keeps our 70 odd litre fish tank at a stable 24 degrees in a fairly chilly room. Use a thermometer or something else to measure the temperature though. The scale on the heater should be used as a guide only.

### ⭐⭐⭐⭐⭐ 







  
  
    Top heater, wouldn't be tempted by the cheaper ones.
  

*by M***S on Reviewed in the United Kingdom 🇬🇧 on 10 January 2017*

This replaced a cheaper heater which failed within 6 months. Great heater. Straight in with no problems and a long guarantee. Did a great deal of research before purchase and this seems to be the best reviewed amongst all aquarium websites I could find. Great price too.
