speaking of my order...i got a UTH from reptiledirect.com thats "supposed" to be good for a 30-40 gallon terrarium. i have a 20 gal terrarium & that heating pad barely takes up 1/4 of it & covers the back left corner only! now i have to order another, larger heat pad just to properly heat at least 1/2 of the terrarium for the warm side...has anyone else experienced this size issue with reptiledirect? im NOT happy with this purchase at all & wrote a review saying so. maybe someone else wil see it in time to purchase the correct size.
