So exited! My band spanking new boaphile cage got here today! It is the 421 coupe with a radient heat panel installed. 4x2x1 in feet. I installed my own lighting (LED aquarium strip) and am using my own thermostat for the panel. This sucker is 100x times more beautiful then I thought it would be! Its going to be housing Lucy, my 16 year old normal female ball python. I'm going to post a comprehensive product review in a couple of weeks to give people whorare considering boaphile plastics some more information.
