curious big company typo

Box and picture shows clearly visible white temperature numbers at the top of heater. I get the heater and no white numbers . Either add white numbers or correct the box and picture. temperature settings are impossible to see-really. I guess i will guess and adjust.

Awful fish tank heater

Stopped working after a month. Very disappointing. Sent a message in, but I haven’t heard back. Chewy is an honest company that usually fixes issues so I am not that worried I just don’t want my fish to be cold

Awesome company

This is probably one of the best companies I’ve ever ordered products from the stand behind their product to be good working or if you have any issue customer returns are very easy the shipping is always fast in on time

This thing sucks!

Heater stopped working within a few days after installing. Also, it doesn't tell you what the temperature of the water actually is, so you would need to purchase a thermometer in addition to this heater.

Chewy is awesome, this heater, not so much.

Heater worked great for nearly 2 months, then it stopped heating. Light was on, but the heating element has apparently died. Chewy is awesome in that they sent out a replacement immediately. This was the first time I've ever had issues with a Marineland product, so it was rather surprising that it died so quickly. I have a Marineland filtration unit that's 5+ years old and still going strong, so I expected this heater to last near as long. It was disappointing that it did not.

Water was leaked into the heater.

Broke within a few hours of using it. I would not buy again, just glad that Chewy could refund me what I paid.
