I'm not sure if they just put the flexwatt in the box or what, but I'm more worried about the groove and probe slot... I can probably ask if they'll put that in whether I order the flexwatt from them or not. I was looking at the ultratherm 11x23 on reptile basics and saw that it was $25. I'm not sure how much shipping would be, but I assume that it would get the cost close to the $35 of adding it on at AP. I'm not sure if Ultratherm is better than Flexwatt or what though. Thanks for all the tips & I'll be sure to post some pics![]()
