110V 100W Watt Anti-Explosion Submersible Aquarium Fish Tank Water Heater

This is a great heater. I bought the 100 Watt version for my 20 gallon tank. The water temperature has been consistently heated to the desired temperature. It is pretty short; which is nice since I have a 20 gallon long tank. The heater suction cups and holder are very sturdy and secures nicely to the side of the tank.

There is only one drawback, the cord is short. This isn't a problem where my tank is located, but I know for others this could be a big problem. Luckily a short cord can be mediated with extension cables. Most people have an extra hanging out somewhere, so problem solved.

All in all, this is a great heater, especially for the price. I highly recommend this product!!! I give it 5 stars because I didn't find the short cord to be an issue.

This prodect does excellently for mixing saltwater. My 5gallon mixing tub is heated consistantly, and it hasn't blown up, boiled the water, or shut off so far! It is easily adjustable, and it works well for such a small amount of water.

The cord is short, but isn't a problem for me since my mixing tub is right next to the outlet. I can see this being a problem for others though.

After researching all over the internet for a good quality heater, this one actually works and does what it says.

thermostat doesn't work properly. i ran it for 12 hrs and it stayed at the temp i got it at.

when i got home, the temp was WAY high and i'm surprised my fish didn't die.

also 'crazy cart' sent the package to my STREET with no house number. item was almost sent back but i got ahold of USPS.

crazy cart would not take responsibility for their error.

one day later it exploded and got glass and god knows what inside the tank. temp also went super high.

my fish hasnt acted the same way since.

i examined the electrical components and it looks very poorly assembled.

it looks like water entered the heater and caused it to short out.
