Holds 1/2 cup, not 1 cup

This holds 1/2 cup of dry food, not 1 cup.  Other than that, its sturdy, but Im returning it due to the wrong size.

It seems like some of the coffee k-cups I buy are a little small and seem like they will fall through the holder.  I balance them so they don't.  I like that this does not take up a lot of space and it holds a good amount for a single coffee drinker.

works okay, but it isn't big enough to hold most cups. it's big enough to hold your average plastic cup and nothing bigger, so no mugs or anything.

Only knock on this is that it's barely big enough for 1 cup of coffee, but they sell bigger ones so not going to deduct stars for that reason.  Works as advertised.

They hold only one cup, if filled to the rim.  Not nearly enough for a normal sized serving of soup.

It has a small size and not convenient to use for big mugs because  the bottom isn't solid and have 2 holes

holds water in the side of the cup. Between inside of cup and outside insulation. Wish I could send it back but missed the deadline.

Definitely can't make 6 cups of coffee with this, not sure why it is marketed as such.  Filling the bottom to the level stated in the instructions is only 1 cup!

i should've read more of the reviews. not as big as i was hoping and it'll hold more like 6 coffee cups, not really 12.

I bought this as a replacement for one that kept re-perking the pot;  but I was misled by the "6-cup" description.  This is true only for 6-oz cups.  For me, it was barely 3 cups, so I gave it away and ordered the "12-cup" version.

I needs to be slightly larger so it can hold the coffee from my wife's keurig on the large cup setting.  Also the top of the syringe handle is a bit to high, do not turn this upside down to dry after washing

After yet another glass plunger broke in my sink, I thought I would go for something more sturdy. This certainly is sturdy, and produces a nice cup of coffee.  What does disappoint me is that the water droplets from washing this container leave marks on the outside of the unit, so it now has a slightly 'marbled' look.  (I hand wash, and usually air dry).  Even when I immediately dry the container, the water still leaves slight marks. It's not necessarily a deal breaker .... just a little disappointing.  It also holds less than my previous '12 cup' plunger.  Other than that I'm happy .... I get my morning cups of coffee, which is the whole point.

I really tried to find a picture with a cup in it for reference before buying but couldn't. I wanted one to hold my daily 32oz Dunkin Donuts iced tea. It seems the inside dimension at the top of the metal ring is actually 3-1/4". With the foam padding inside this made it even smaller... too small to let my large cup sit down far enough. It took a little work but I was able to scrape out the foam and now my cup goes in good enough. Now that the foam is gone the ring does develop a lot of condensation (not sure if the foam makes a difference on that). It was installed fairly easily. The cup, even without the foam, seem to stay pretty well in the cup holder even on the bumpy streets of NYC.

The 1-Cup glass container holds almost 2  cups of liquid.  A smaller container would be better.  The red lines are very close together because of the size of the measuring cup.

It's easy to use and makes a pretty good cup of coffee. I had trouble at first making the coffee strong enough for my liking but realized this could be remedied with a finer grind and using plenty of coffee. My qualm with this product is that it's not actually big enough to make two cups of coffee. It's maybe big enough for 1.5 cups of coffee. I went for the large size because I wanted to make two cups at once and this doesn't accomplish that.

Crossover gadget combines drip and French press elements to make a good-tasting cup of coffee. Sadly, does not fit atop either of my favorite mugs; balance precarious, and I do not want to have to hold it while it drains. Works with smaller mug diameters. Two sets of ridges designed to fit inside/outside different size mugs seem unnecessary; would be better without them imho.

6 cups? I can barely make 2. It works well at least.
