Question: Is it a harder plastic than the older Rubbermaid containers?
Document: This product is a very nice improvement over the older models of Rubbermaid containers. The change is the clear bottoms which allow visibility when used for storage in the refrigerator.
Most of my plastic containers are opaque; these are absolutely clear which is much more desirable. Great job, Rubbermaid!
It was time to replace my old, stained containers so I did a little research and landed on this Rubbermaid set. I was torn between buying these plastic containers or going glass.
See through, so leftovers are easily visible. The set is also interchangeable with my other Rubbermaid containers that are NOT see through which I was hoping for. Love Rubbermaid plastic sets. Keeps food fresh, plastic is thick and sturdy, easy to put on andtake off lids. Great quality, and nice feel. These really last (if I can keep them from disappearing), but really got tired of the disposable and dollar store containers. So it is worth it to me.
We've collected various sets of food storage containers over the years and lately have been using the less expensive disposable ones. Seeing how the plastic pits and warps with those made me nervous so I recycled them and bought this Rubbermaid Premier system.First of all, the clear plastic is a much higher grade and resists stains, pitting, and warping well. The clear lid helps in seeing what food is in it and the soft rubber seal makes closing the lid nice.
I thought I would give these a try so I could get away from plastic. The containers worked well at first. I wash the lids by hand because I have had other plastic lids twist from the dishwasher. I did like the small containers for leftovers, but after a while the lids would not seal properly. The lid would keep popping up on one of the corners. I threw those lids (2) away. I'm just not that pleased with them even though I've never had problems with other Rubbermaid products.
Rubbermaid 12-Piece New Premier Food Storage Container Set -- Cool color red. Great looking containers! Love the stackability. 12-piece set of containers made with Tritan plastic that resists stains and odors. Set includes 3-cup and 5-cup containers plus two each of 1-1/4-cup and 2-cup containers (all with lids). Flex & Seal lids are easy to seal and remove; Easy Find lids snap to bottom of container and to each other.
Any time a manufacturer uses the term &#34;new&#34; or &#34;improved&#34;, lookout. I have a number of these premier containers and wanted a few more of the smaller sizes offered in this set. The tops are NOT made from the same quality of flexible, easy off, easy on gasket material as my older ones that have stood the test of time.
In an effort to cleanse my kitchen from the &#34;unwanted plastic&#34; I replaced it with the Rubbermaid set. It has been the best decision. These are perfect sizes, air tight and non-spill. Also helps in saving space in the refrigerator.
I purchased several of these sets and am so disappointed. I just threw another container away today as I unloaded my dishwasher & it had cracked! I owned the older version with the grey lids and switched to the red rimmed BPA free ones. Was impressed by all the positive reviews before i bought them. I loved how the lids stacked together and how the containers stacked to take less storage space after I purchased them.
Answer: Yes and red sauce doesnt stick to it.
