I wanted to share an example from just this week of why it's absolutely worth it to have patience with the email response time of ProProducts.
I mentioned that I've ordered quite a few RHPs from them in the past. I am in the process of ordering another one right now. I went through the usual process of answering the questions about enclosure type, conditions in my snake room, etc. A few days later I got this email from him:
"Will this cage be in a different location than your other cages? You always said the room the cages are in was in the mid 70's or higher and this time it can get down to 70°. Also will this cage be an upper cage in a stack or is it a bottom or stand alone cage. You are borderline between two sizes and the reason I am asking these questions."
It has been almost two years since I ordered an RHP from him. But he went back and checked my previous orders and noticed a disparity of 5 degrees F in my previous responses about room temp versus the most recent order, and checked in with me about it.
That's just one example - I've got several others. Bob is the real deal, and this combined with his guarantees about safety and performance are why I'll never get an RHP from anyone else.
