Works perfectly in my Betta bowl. Keeps the water warm consistently, even in a cool room. Easy to install and doesn’t interfere with the gravel. My Betta is very active and happy with the stable temperature.

Good for small tanks. Heats up quickly and maintains temperature well. A little small for larger setups, but ideal for a single Betta bowl. No issues with the plastic or placement.

I’ve used it for three months now and it’s still working fine. The water stays warm without overheating. Simple design, no leaks, and fits perfectly under the gravel.
