Keep water at 78 Degrees Fahrenheit
I bought it to use with two Mississippi Map Turtles. Since i have owned it, the water has not gone below 78 Degrees Fahrenheit and it's in a 30 gallon tank. It automatically shuts on and off as needed. It's safe enough to have the turtles climb on it and not hurt them. Great product for the price, I found the same thing at Petco and it was fifteen dollars more.

Boiled My Fish
I notice my 29 gallon fresh water tropical fish tank was very hot and fish were dying. The thermometer was pegged at the top. My Tetra Heater 10-30 'on' light was on. I unplugged the heater and began cooling the tank with bags of ice. The next day I tested the Tetra Heater 10-30. It quickly brought the water to 130 degrees. I notified the manufacturer who responded with a canned reply stating that if I returned the Tetra Heater 10-30 to them a copy of my original receipt, they would send a replacement. Perhaps they have an upgraded model that will boil fish faster. No thanks!! That will be my last Tetra product.

    Stopped working after 9 months
    Purchased 9 months ago, stopped working now. I need to mail it for repair/replacement which would cost me almost same price as the unit. So going to buy a different heater

    Great for the price.
    Decent heater. I would say that it's perfect for a 20 gallon tank. But do remember it's only good for the price it came with. It does take quite some time to adjust to the required tropical fish tank temperature. If you want better results I suggest you get a cheap adjuster but be careful.

    Almost killed my turtle
    I bought this heater to keep the tank warm for my new baby red earred slider turtle. He is in a 10 gallon tank. I came home from work to find my water at over 100 degrees F. The heater never shut off. My turtle is barely alive after being cooked in the hot water and I don't know if he will survive. This is the second time I have bought one of these heaters and both times the water temperature spiked to dangerous levels, the first time it spiked to 90. After the first time I thought maybe just that one was defective. But I will never buy this product again and risk one of my animals' lives.

    Tank Heater
    I purchased this item about a week ago and I am very happy at this time. Price was very reasonable although online price was a little less than in store price. Item directions make very easy to install.Actually had enough money to buy extra fish food.My fish and I are very pleased.

    pretty good
    i bought 1 of these for a lidless 10gallon tank and it keeps it at a steady 78. i bought one for a 30 gallon tank and it also keeps it at a nice 78 as well (though the bigger tank sometimes dips to 76 before the heater comes on). was worth the 15$ i paid for both. best bet to get it to work well i found, is keep the heater near the bottom of the tank. setting it horizontal keeps the heat even for the big tanks too
