It’s a poorly built product. It's hard to send a video of you pushing a button that doesn't work.
The suction cup attachment method is nice. I like how well it hides in the hidden compartment of the flex 9. The only drawback is the size.
The thermostat is accurate on this unit. The heating dial is easy to click and turn. Just start on lower the lower setting and work your way up over a few days to desired temp.
Perfect minimalistic design for all-in-one nano reef acrylic tank. It keeps the temperature very accurate and heats the water quickly when i cleaned and refilled the tank.
The temp settings on the top are off so use another thermometer to set to desired temp. It doesn't matter how high i set the temperature for this 100 watt fluval heater, the tank temp never gets above 76-77.
The m200 heater looks like a glo stick in my tank. The top of the heater leans out of the suction cup. There isn't any place for the top to come out if you have a fluval spec aquarium.
The package says submersible. To me that means *the whole thing* can go underwater. That makes no sense to me and is borderline false advertising.
Mostly unreliable reviews. Do more research before proceeding
