The heater works reliably and maintains a steady temperature in my 20-gallon tank. The LED light is helpful to know when it’s active. It’s sturdy and the glass doesn’t crack even after several drops during cleaning.

I installed it vertically and it’s stable. The temperature stays consistent, and the auto shut-off feature gives me peace of mind. Only minor delay when first turning on, but it settles quickly.

Great build quality. The quartz glass is durable and the suction cups hold well. I’ve used it for over a year and it still performs as expected without any issues.
