Perfect size for Betta Tank!

I actually bought this heater to go in my wall tank but it only suitable for up to 10lts & my wall tank was 11lts! Never mind as I used it in my small Betta fish tank & size was perfect to easily hide behind a plant so main focus is on Betta fish or decoration - not a huge heater like they normally are! Temp is set at 26 degrees & does a good job of regulating water temp without manual setting - does click on & off with red light showing when it's on! Really pleased & recommend for small sized tanks - think it would be good for using in kids tank so they aren't tempted to play about with thermostats control as there isn't one!
