I love my Glasslock containers. I use them everyday. They are air tight, they can be put in the microwave and dishwasher. I recommend these containers!
These glass storage containers I got are great. They are leakproof, because they have a silicone seal on the lids that lock into place. I use it to store all my foods now, and the glass containers can be used in the microwave (not the lids though). There is no BPA, and I don't have to worry about plastic chemicals leeching into my food. The only reason I didn't give this a five star rating is that the containers are not oven-proof. I just found out they have a separate line of oven safe containers.
