Spectrum Diversified Under The Shelf Mug Holder, Optional Under Cabinet Mounting, Slides Over Kitchen Cabinet Shelves, Holds Up to 8 Coffee Mugs & Tea Cups, Chrome

If you have traditional coffee cups (the ones that look slightly larger than a tea cup) then you can get away with just one. If you have American sized coffee cups or larger (12oz+), get more. A 10 oz cup is about the limit if you expect to get one on each rung. I managed to fit my 16oz cups on each rung but it looked awful (very cluttered). However, once I set it up for every other rung, it looked fantastic.The quality is good. I have 1inch thick open shelves and this gripped them nice and tight. If you have something thicker or need to close a door over it, I would suggest a mounted system or hooks instead. There are two screws included if you feel your shelf may need extra reinforcement, I felt they were unnecessary in my case. Overall, a really great product!

There are more hooks than needed so you can fit the highest ammount of unusual sized mugs. I bought two and fit 6 regular mugs on one and only 4 giant mugs on the other. My narrow width shelves are set in so the rack slips on and does not get in the way of the doors. The mugs hang freely which means they lean forward so I can't slam my cupboard doors or I'll smash my cups but who does that anyways? The doors close easily. The metal holder does stick up on the upper part - however it's symmetrical so large flat plates fit nicely, or bowls centered. But I wouldn't put more cups above it without laying a flat cutting board or something similar.Overall the best looking mug racks - durable, well balanced, and above all else - functional!

If you can find a shelf that works with this holder, it's a really great little organizer. I wasn't able to use it in my kitchen cabinets, but it works great on my pantry shelves. It is sturdy and is holding 10 tea cups easily. It would not hold 10 mugs, because the mugs were too big to all fit on the hooks.

Very nice and sturdy. Price is pretty competitive with in-store retailers. The rack fits snugly and securely onto the shelf, almost too snugly. The part that fits on the shelf is coated with a thin, clear layer of plastic to ensure better adhesion. My shelves are not quite 1/2" thick, but I had to 'open' up the rack to get it to fit on so that there was no excess poking out in the front. Try putting it on the shelf first to decide if you need to 'open' it up a bit more though.

Nice for the price I paid. No problem fitting on shelves, it was perfect fit for me. Disappointed that my mugs did not fit as I had thought. Hooks are for small cups--even the box read "cup holder" although advertised as "mug holder" hmmm. I noticed the price has increased for this item. Had I paid the new price I would have returned them--I bought two--at lower price I still consider this a good deal.

It will only hold 3 cups each side

There are a lot of questions on this item, pertaining to how thick a shelf it can hang on, etc. I found that the 'slip over' function fits a shelf made from a standard 'One By" board (so 3/4ths of an inch thick, approx 2.5cm) I used it inside my kitchen cabinet freeing up valuable shelf space, and the door closes just fine with it in place. As the description indicates, there are 4 spaces for screws if you prefer to mount it to the underside of a set of cabinets. A lot of reviews noted that the hooks are spaced for small 'tea' cups, which is accurate, meaning that using the standard american style 'coffee' mug you will only be able to hang 4, maybe 6 mugs on this rack if you are clever. It seems sturdy and well made, the finish did not have any noticeable flaws that I could detect.

Just got these in - and I agree with other reviewers that they are not good for sliding onto standard shelves at all. Measuring, toward the joint, there is only a half inch between the arch of the holders and the bracket. I got it about 4 arches in before having to give up (with the outside portion no longer lying flat in doing so). I also broke one trying to open up the bracket enough to slide the last arch on. It looks like some of the mounting posts for the screws are bent too far inward. My shelves are 3/4" thick.Gave up, ended up screwing them into the bottom of the shelves, which I had purposefully bought this particular product to avoid. It's nice looking and works in half its capacity, but DO NOT PURCHASE if you're hoping to slide this onto a shelf more than 1/2" thick. Too big of a gamble that you'll get one that won't slide on.EDIT: 2 to 1 star.They hold about 2 - 3 coffee mugs on each side (so a total of 4 for me) depending on the depth of your shelves.
