New setup

Im looking at getting the rubbermaid all access bins for my balls does anybody have any experience with these tubs? Ive seen some great reviews on other sites but i have faith in the ppl here lol. Any and all info would be great. I would be heating them with 6in flexwatt run in parallel to a zoo-med stat (i know i know cheap=bad).

I've never seen these in person, but from looking at the pictures online here are my first impressions:

• The front panel looks less than secure. I would put money on an escape/pinch injury unless you have something else in mind to keep it closed.
• The bottom/sides aren't flat. I prefer tubs that are flat because they're easier to clean and easier to heat sitting directly against the tape.
• The "fin braces" on the inside to support the handles look like they could be a safety concern. I would trim them smooth before I put a snake in there.

They look like a good concept, but the reality of using them would be too much for me.
