I left it in a hikers box after carrying it 30 miles.
Slow as hell and 15 mind numbing minutes later a cup of weak cold coffee - (cowboy strained filtered w/ the "drip" is served up cold as well).
light coffee options are still...
1)unfiltered cowboy coffee - gritty
2)instant - my choice. - reliable
3)bandanna filtered - messy
4) portable generator + cappuccino machine - considering it.
Left the GSI drip in the hikers box somewhere in Northern Virginia. (if you found it - I left it and um... "lucky you").
Great device in theory - not in practice.
Tip- 1-2 Carnation instant breakfasts (mocha or vanilla) and a heaping teaspoon of instant - hot water. Caffeine and nutrition rolled up into a sweet hearty shake! Good luck 09 thru hikers - EFF'N rain - you poor poor b-st-rds - urban.
P.S. sorry GSI - on the other hand the "soloist" is fairly sweet -
