Let's start with what the company has to say about each product.
The Instavac storage container:
Introducing the world's most effective vacuum-sealed food container set, the Ozeri INSTAVAC Green Earth Food Storage Container Set. Completely BPA-Fee, the 8-Piece Nesting Set with Vacuum Seal and Locking Lids is designed to SAVE FOOD -- simply press down on the lid to remove excess air that spoils food; SAVE MONEY -- pays for itself and more by keeping food fresher longer; SAVE SPACE -- each container nests for convenient, efficient storage; SAVE TIME -- each container is microwave, dishwasher and freezer safe for long-lasting use. Unlike other products, the Ozeri INSTAVAC Green Earth Food Storage Containers use a patented valve system that allows you to easily remove excess air, so growth of naturally occurring bacteria is greatly reduced, and food stays fresh longer. With the Ozeri INSTAVAC, instant vacuum freshness is created without pumps, motors or confusing parts. Simply press down on the center of the lid and air is forced out through the one-way valve. Creating a vacuum requires minimal effort. The patented valve system is also designed to automatically release air pressure when it builds up in the microwave, so you never have to worry about spills, splatters, and bursting. The BPA-free, stain-resistant, shatter-proof, Ozeri INSTAVAC Green Earth Food Storage Containers are as transparent as glass, and safe to use in microwaves, freezers and dishwashers. Each container features a handy date dial that allows you to record when food was first stored and monitor days kept in the refrigerator, so you'll never have to worry about remembering how long each container has been in the refrigerator. Each container is also made with a wave patterned bottom that keeps cut fruit and vegetables elevated from the deteriorating effects of water and juices which can collect at the bottom over time. Your satisfaction is guaranteed and backed by Ozeri's industry-praised, no-hassle warranty and customer service.
Here's what I think about it. I love the sizes. As you can see there is a nice variety present in the set. And the fact that they nest into each other is awesome.
The product works great! I have a bunch of random tupperwares and I do believe that this one lasts longer than the others. Although I've not done the ultimate test and packed the same stuff inside to see how long it would last verses another kind.
I love the date ring on the top. It's really helpful when I remember to do it. LOL. My memory is kind of screwy sometimes and I'm in a rush. But definitely a bonus!
The only problem I have has nothing to do with the design or product per say... it's more of a constructive comment. I have two little kids (my son is 6 and my daughter is 2). The little ring on the inside that keeps the suction going can easily be poked through by little fingers. Something that I hadn't even thought about until my son shoved his finger through one of them. >,< So maybe have them come with back up rings or sell back up ones or thicken the plastic a little bit. I don't know how to solve the issue, but merely putting it out there. Most people wouldn't have this issue because they aren't going to be ridiculous and shove their finger through it.
Besides that, I would highly recommend this set for anyone looking for a good tupperware set.
The Ozeri Duo Ultra Salt & Pepper Grinder utilizes a powerful eco-friendly ceramic gears and a space-saving design that combines salt and pepper chambers in one grinder. The Ozeri Duo boasts high quality stainless steel and an ergonomic non-slip grip for ease of use. The removable lid includes a slider to provide easy access to the salt and pepper chambers while minimizing spillage common to other products. The Ozeri Duo Ultra also features two adjustable knobs that precisely adjust the grind to your liking.
Here's what I think about the grinder.
Firstly, it's an attractive element to have in any kitchen. It's really nice looking.
I had a hard time finding the salt and peppercorns to go in it (my camera broke before I could find it! LOL, so no follow up photo!).
I actually removed the little plastic ring thinking it was part of the packaging, but luckily I read the directions before I got rid of it! *Phew* Mine hasn't broken, but I could see how people would be worried about that. It does seem like a piece that could've been made out of another material to ensure that it lasts.
I've had no problems with how it functions. I can get the pepper and salt to come out in the coarseness that I want without any issues.
Now, for me, that's a win! It does what it's supposed to do and looks good doing it. I've no clue if it will last years, but right now it's working good! Definitely a good buy if you're in the market for a duo grinder!
