out of this world
This is a must have for any kitchen. It is a real time saver. I don't have to spend 5 or 10 mintues looking for the spice I need. I highly recommend this to everyone. It is a well made item. GET ONE. Would make a great gift for any kitchen.

the most space-efficient spice rack I've ever seen
Accommodates a good variety of bottle sizes, although the top rack doesn't have quite the clearance of the lower two. I'm quite pleased. The only thing I'd change would be to include some labels in case you're like me and put the herbs in one rack, the spices in another and the mixes in the third, and you want to pull out the right one on the first try.

Genius solution!
I recently moved into a new studio apt. with a teeny-tiny kitchen and not a single drawer in sight. I hate having my spices out on shelves because everything that's exposed in the kitchen tends to be covered in a sticky greasy film withing weeks. So I was looking for a rack that would let me keep my spices in the cabinet and give me easy access.
After looking around for a long time and almost building my own under-cabinet spice drawer, I found this great product. It fits into most cabinets and lets you store a whole bunch of spices while keeping them organized and easily accessible.
Pros: great concept, works as described and expected. stores more spices than I actually owned.
Cons: has a tendancy to tip forward when you pull out one of the drawers with heavier spices (in glass containers for instance). BUT, if you have a shelf directly over the rack it will not tip forward, so that's an easy fix. I guess you could also always secure the back of the bottom of the rack to the shelf with a bit of self adhesive tape, that should do it.
Bottom line: great great product. love it and recommend it.

great design
Like others, I really like the design of this but am dubious as to how well it will hold up over time. It probably would have been better made of metal than plastic. When a loaded drawer is pulled out there's a lot of stress on little plastic pins...especially if you have glass spice jars. It seems to be the only thing anything like it on the market though and the idea is brilliant.

A Bit Delicate but Otherwise Great!
I love this spice rack! As mentioned in previous reviews, they are a tad delicate. You should pull them out somewhat carefully. But overall they work well and stay firmly put on my shelf. I did switch over to all plastic bottles to reduce weight. It hasn't tipped over once.

I find this way of organizing spices a great way to see with a quick glance what I have. After years of a revolving spice rack, I love these and recommend them.
