This is the AeroPress "AeroPress Go." It's a portable coffee dripper. I tried it once at home when I received it, but I haven't had a chance to travel since, so I've kept it in the box. I'm selling it now because I don't have any plans to use it. The 100-count filter pack has been opened, and I've put several dozen filters in the filter case. I used one filter for a test. It's in generally good condition, but please refrain from purchasing if you are sensitive to used items or if you are looking for a perfect product. I will carefully pack it with bubble wrap and ship it promptly. Thank you.
