I cannot stress enough how good these are except to say even more appreciated in this day of "junk manufacturing." I have tried other Lazy Susan turntables including most recently ordered 2 in memory-error offered by "mDesign" and I might as well put things on a dinner plate and try to turn it. (Junk.) I had ordered two of these iDesign ones last year and they spin beautifully, with or without weight on them. Staying with what works and discovering my brand error, last week I ordered two more of the iDesign turntables and they are again perfect. Well made through and through including the factory-fitted packaging (only mentioning that because it's a sign of the distributor brand not cutting corners). Granted these are more expensive than similar appearing lookalikes but they will last for years and they Are Worth It.Info: They are 11" inside usable diameter, and the effective part of the lip is 1/2" tall which is enough to stop things from sliding off but low enough not to snag retrieving tall things with limited headroom. Give it a push and it spins evenly and smoothly on its ball bearings. And sturdy! I am using them for tall heavy bottles of sauces and oils in a cabinet with unevenly distributed weight around the turntable and it spins properly. Also in my awkwardly-high fridge top shelf (ditto the unevenly distributed weight). Also have one on my center console for things I constantly need and yet another for my most commonly used spices. In other words, tried and proven, they have increased my organization and efficiency in the kitchen... a LOT.I hope this review saves others time and returns hassle that I had to spend before finally finding these. I have gotten away with inferior products of other types where the lack of quality doesn't matter that much, but a turntable? It has to be designed and made well.
