The easy way to brewing coffee and lightweightGreat packable coffee maker. I got it for backpacking.Love this!! I used to use a metal perforated coffee strainer and it would get clogged after 2 times and regardless take many many minutes to drain. Yeah, I should wash it often but since I drink coffee several times a day, it felt time consuming. So this helix strainer is perfect as I get my drink in less than 2 mins, ready to run for my next meetings.I love it a lot. I was looking for lightweight and small coffee maker for my outdoor activity. This is the one because it’s a foldable and super lightweight. The idea of the coffee maker is genius! It’s a made in Japan quality is great. It’s good size for 2 cups or big one mug size coffee.I bought this for travel, as it packs small and flat, which is great. Clever design, and is one of the few collapsible coffee drippers on the market that fits cone shapped Hario paper filters, as opposed to Melita filters that have a straight edge/seam on the bottom. It is also the most compact for travel that I have found...it folds up small and completely flat, so barely takes up any room in a backpack or suitcase. The size 2 Hario filters fit a bit large in the dripper, it's really designed for size 1, but size 2 does work fine. As others have reported, the bottom of the filter does hang down an inch or so below the bottom of the dripper, so it does tend to sag into the cup, but I usually use a tall enough cup that this isn't too much of a problem, but a simple design tweak of making the bottom coil a bit smaller in diameter would likely fix the problem. I haven't tried using it for camping, but I could see that heat retention in cold weather would be a problem, as others have also reported. For indoor use, this is not much of a problem. My biggest complaint is the price...$20 seems a bit steep for what is essentially probably no more than $1 worth of stainless steel wiring, but with no viable alternative on the market for Hario filter users like me who want a collapsible cone dripper for travel, I am very glad that this item exists!Yeah, it's actually great, and I wasn't going to buy one of the many knock-offs from eBay, but why the price tag? It's a bit of wire bent into a cone shape. Real coffee out on the hills though, that's something. Would recommend.
