No!! Don't do it!!
Sorry, I am alarmed at the price as well as the product. The problem with those heaters is that they are going to raise the temperature the same amount whether they are in a room that is 68 degrees or 75 degrees. For that price, you can get something like the hagen mini elite which is adjustable. They are available at amazon and many other places, including www.kensfish.com
. Kens--and probably amazon--also has the large size krater keepers which are 3 gallons if you want to upgrade to something larger.
There are also many other heaters which people can recommend, that's just the one that I use and have been happy with.
