Hi all, I realize I'm quite late to the party here... Life has happened to me in a big way in the part few years,
but hopefully from here onwards I'll be able to be more active and contribute to the board as much as I'd like to. Better late than never, I suppose?
Impressions of the AirScape for me were initially quite positive: great, solid build quality and functional design. However there were two sticking points that arose for me off the bat.
First, the type of plastic used for the plunger handle feels... "soft?" for lack of a better word. Or put another way, it feels more plastic (as in the scientific definition, pliable) than I would like in a key functional component. I suppose I wanted a harder, more solid feeling to it. This issue is definitely a personal one, and shouldn't be seen as a general condemnation of product design or general quality, though!
Second, however is slightly more serious. The rubber foot on the bottom of my unit is off-center, enough so that it causes the AirScape to rest at a very slight angle. Almost unnoticeable, but when you flip it over, you can see very clearly that the foot is outside of the slight circular depression made for it. See from the picture what I mean:
Anyways, all that aside, the AirScape does an excellent job of making and keeping an airtight seal. I tested it with some Long Jing for about a year, and the color of the control (stored in a regular double-lid tin) was two or three shades grayer than the leaves stored in the AirScape. Aroma was decreased, but much less than I'd expect from storing a fresh green tea for a bit more than a year. The control was almost undrinkable in that amount of time, pretty much flavorless after the first infusion. I was able to get three solid infusions out of the AirScape stored LJ, using a 150mL gaiwan and 185°F water, and a 4th if I upped the leaf/water ratio. Unfortunately, I don't have pictures of the leaves or tasting for you guys, sorry about that!
