SIM Incubation Boxes...opinions?

I noticed these incubation boxes over at ReptileBasics:http://www.reptilebasics.com/sim-incubation-box

They claim to possibly give better oxygen absorption to the eggs. Seems interesting but I'm hesitant to gamble on a new incubation box with a clutch of eggs. Does anyone have any experience with these particular incubation boxes?

I use 7qt sterilite locking lid tubs with perlite, water and light diffuser panel and the eggs have lots of air surrounding them, those are nice tubs but I can't see spending that much on them because of those advertised claims "that I'm skeptical are even true".

The tubs I use cost under $4 to set up and work awesome, just sayin :)

And what if your eggs are stuck together? kinda hard to place them in the rows.
I like the set esp the one for gecko eggs, but for now I'll stick with my sterlite

I hate to say this because I love everything else Rich sells.

I bought a few of the boxes to try them out and I don't like them at all. They're way too small. If the eggs aren't perfectly horizontal they won't fit in there. The lid also has a tendency to droop down and touch the eggs, which is very bad if condensation is collecting on the top. Save yourself some money and just use a regular Tupperware box with some egg crate on it. Same principle.

How secure are eggs on these flat surfaces do ya'll find? I'm a fan of the added security of having the eggs halfway buried in some type of substrate - probably because I'm not the most coordinated person. I'd be scared of bumping the box and having an egg roll over or some such thing. The sim ones look a little cramped but do have what looks like some kind of anti-roll horizontal bars at least.

If you go to the dollar store and pick up a bag of plastic clothes pins your set, just clamp them to the light diffuser panel and presto, no rolling eggs :)
After a week the eggs flatten to the egg crate a little and then the clothes pins can be removed.

Excellent solution, thank you.
