Poor fit for grounds.

I tried the Airscape canisters for ground coffee. The grounds apparently infiltrate the bottom rubber seal, causing an imperfect seal, and the coffee lost its freshness after only a few uses.

The filter does not go down enough by far. You waste a ton of tea or coffee. Not as good as the good old bodily coffee pots i used to know.

This has a flat filter basket, not conical. Grounds from grinder are deposited on one side. Water flows across and around grounds, even when set for 10 cups (maximum amount of grounds). Needs redesign with conical filter. Returned for refund.

Hard time getting wet grounds out.  Have found less expansive brands that work well.
Would not buy again

Really really poor construction.  Does not keep the coffee grounds from being mixed with the coffee.  The plunger is way to small for the the container.  And the website for support is some kinda scam site.

I was VERY disappointed to find that these were foil packets of loose ground coffee. Previous posts had stated they contained filter packs, but this must have been for some other product. I put a 4 cup coffeemaker in my guest bedroom, and intended to stock the supply basket with filter packs (as they do in most hotels). Now I have to buy filters and hope that my guests don't create a mess with loose wet grounds.

Its does an okay job grinding. But the grinding pod is not conical which causes the coffee beans to be unevenly ground (really fine at the bottom and big coffee bean pieces at the top). Would not buy again.

Metal parts started to rust within a week of use. Press does not reach antwhere near the bottom of the container. Mesh is not fine enough for fine or medium ground coffee

I bought this 50 pack and threw almost all of them out. They are overfilled and when they get wet, grounds go in all directions. What a mess.

Great concept but bad seal between the plunger and mug.  I've tried numerous ground sizes with this mug and I consistently end up with a mouthful of coffee grounds in each sip.

construction seems decent.  the main reason for only 3 stars is that it is somewhat misshaped so the filter on the press does not seal all the way around.  this causes grounds to get through.  at first, i thought it was because i was at the bottom of the bag of coffee.  but, after getting a new bag, i'm still having the same problem.  i just pour the coffee through a strainer and problem solved.  it's not a huge deal, but i think it shows that quality control may not be up to par.

Not adequate brew temps. Measured 170 straight from the head. Need to stir it up about half way to get all grounds soaked.

Looks like the real deal, but leaves coffee grounds in the bottom of every cup.

I had a WIllows and Everet filter that broke off the base.  This filter sets in separate from the base, so is less likely to break.  However, the fit and finish of the filter is not up to snuff, allowing fine powder grinds to filter through into the coffee. It appears that there is a gap on the bottom that allows this to happen.  The size of the filter is also smaller than other filters I have used, necessitating the need for 3 fills when using my large cup in the morning.  I have take to using the stand with the other filter from before, creating a Frankenstein filter that works very well.
