Query: inaccurate height description

Overall, this is a great product. I am frustrated, though, because the description of it says that its height adjusts from 16 to 34 inches, but when I received it, it only expands up to 28 inches. I reordered, and again received one that only expands up to 28 inches. I had measured, and wanted the one that expanded up to 34 inches, but customer service had no way of ensuring I got the product advertised. Be aware that yours, too, may only expand up to 28 inches.
