I lost the cap to my aeropress when I took it camping, and bought this as a replacement so I didn't have to buy a whole new one. Works just fine.A one to one replacement as far as I can tell. Fits perfectly and seems to be holding up wellDon’t know how I lost the last one but I did. This one works the same. Glad I didn’t need to but an entirely new set up. I am in a hammock and a little drunk. But my aeropress works again!This did just fine with my Aeropress, but I will say it has the tendency to make a bit more of a mess than the original piece.Yup! When you need a replacement after you accidentally threw yours away in the garbage! Perfect for the Aeropress!No issues, used this with a new metal filter to reduce our waste from paper filters. Worked pretty well.This fits and works like the original piece. Works perfectly!I lost my original cap, and this is a great repalcement. It's almost identical except it takes a little more effort to screw it on to the base. It must be just slightly thicker, by a fraction of a millimeter.
