The rack is great BUT the low rating comes from the listed specifications as fitting a 3.5" diameter spice jar. The space available is closer to 3" so I had to send mine back as my jars are exactly 3.5" and if it was a tight squeeze I'd make it work but 
 the listed measurements were WAY off...I can't squeeze the jars a half an inch to make them fit. If you have 3" jars, they should work...don't accept the listed specs as accurate.
