difference in AP racks

Can someone explain me the difference between the Sterilite and Iris racks that animal plastics provides. specifically the adult ones so the cb70, 1755 series and 1860/1960 series. Just trying to figure out why the price difference and if the cb70 is really worth the extra money over the Sterilite.

Rack using Iris tubs are often worth the price difference.

The problem with sterilite/rubbermaid tubs is that sterilite and rubbermaid re-design their tubs on a regular basis making it difficult to find a replacement tub if needed, their tubs also have groves at the bottom, whereas Iris are flat and smooth which makes them easier to clean.

You might also want to look into those racks using vision tubs http://www.cserpents.com/C_Serpents_...K_SYSTEMS.html

In addition, I personally feel the iris tubs are also more durable, they seem to use a thicker and more shatter resistant plastic, but I can't really back that up with any numbers or anything.

The Sterilite 1860/1960 AP racks cost the same as a the Iris CB70 racks. They're about the same size too.

The 1755 series rack is smaller. 23" tubs instead of ~34".

But yeah, Iris/Vision 70 tubs are the best.
