I am considering buying these for BP's but have a few questions/concerns.

Question one.
Are these racks actually large enough to hold adult BP's?

Question two.
The flex watt is on the back. Wouldn't it be better suited on the bottom of the shelf?

Concern one.
The flex watt is "welded" in place in the back. It's sandwiched between the plastic. If the tape fails, do you have to destroy the rack to get it out and replace it? Also, wouldn't this pose a fire problem with no ventilation?

I would like to hear from anyone who has one of these or who has seen them "in action".

Thanks.
