The jars and rack are great, but the lids are very cheap and ill-fitting. Part of the problem could be the plastic rings on the jars, but the lids keep popping up and don't make a good seal. They also have hinged openings for shaking and pouring that are just connected with the plastic they are made from, so it is damaged every time you open and use it, and they will eventually fall off. It's too bad such cheaply made lids are included with such nice, heavy jars and pretty rack.
