I've been roasting my own coffee for 20+ years and have used all kinds of brewing methods from vacuum pots to french press and everything in between. Mostly I have always used french press because I just preferred the taste of the coffee but recently in the past months I have been wanting to find something simple, not that french press is difficult by any means but I just haven't felt like bothering with it lately. So I was thinking of a drip machine (NOT a Keurig) but it had to be one that heated the water to the correct temperature and as most coffee aficionados know, those are few and far between for some reason. In addition, I wanted a small machine like a 4-cup machine. We used to use an 8-cup Technivorm so I was familiar with them and we still have that machine around somewhere but making less than 8 cups is not optimal. My husband uses the french press so we never have any reason to make 8 cups of coffee.So I happened to stumble upon this machine which somehow I had never seen before and the more I read about it the more it sounded like the perfect machine for us. I read a lot of reviews and noticed the common complaint was the hole in the filter basket getting clogged, but that didn't really seem like a big problem and since most people seemed to love the taste of the coffee (and those few that didn't, who knows what kind of coffee they were using anyway), I decided to order the machine. I've been using it now for about a week and a half and it's been perfect. The coffee is great and it's so easy to make one cup of coffee. No problems with the filter basket hole and I don't see why there ever would be because all you need to do is hold it up to the light and look at it or run water in the basket and make sure it's going through.So I would definitely recommend this machine if you need a small coffee maker, it's far far better than the k-cup machines.UPDATE: 2 months after my original impressions, I've gotten into the groove of using it and how to get the most out of it. I've concluded that setting-and-forgetting this machine sufficiently renders great coffee without altering anything out of standard coffee making procedure. The damp coffee grounds left after brewing do indeed still form a cone-pyramid shape, but I haven't noticed hardly any difference from when I stir the grounds during brewing 2-3 times vs. not touching it at all. This bumps the machine from 4 to 5 stars. This is the best single serve machine on the market. Now read my review below and keep in mind what I just mentioned.I'm going to be rather critical of this machine since I spent a pretty penny on it. But if this gets 4 stars, 99% of other auto-drip brewers probably get 1-2 stars.This machine is fantastic. I've put about 15 cycles through it, and the ones where I measured temp, they all came out to ~198-200F, and all went thru the brew process of 300g/10oz water (medium fine grind) in about 5 mins total, from flipping the switch to the last drip, 5:30 at the longest. So it does what it says it's supposed to, which is great.A few design features confuse me. The lid that sits atop the reservoir and drip cone sits a little precariously (it wants to tip if you touch the cone side). This is minor, but I feel like maybe a hinged joint on the reservoir side and the cone side would be more robust. Additionally, the drip spout is a simple U-shaped tube (longer on one side). I wonder why Technivorm didn't follow the design of the other higher volume brewer models and design a shower-head design instead of just a dripper that drops water right into one spot the whole brew process instead of the even showering you see in bigger models. I don't think this would necessarily lead to better flavor, but from what I know about pour-over coffee, a more even wetting of grounds is always better. The grounds do seem to all get wet, but once dry, they form an inverted cone/canyon once the brewing is done. I stir the grounds/water after about 30 seconds to hopefully combat this possibly negative effect. I'm too fiddly to resist, but the coffee tastes great either way. The reason I included this tidbit is that if you pay this much for a brewer that is supposed to be mostly autonomous, there should have to be minimal interference for good coffee. This is probably why I'm putting 4 stars instead of 5. If someone provides me with enough compelling evidence that this doesn't matter, I'll change it to 5.The coffee is excellent. Without the cup preheated, and waiting about a minute after brewing ends, the coffee is at the perfect temp for drinking. The mug is nice as well, and the filters seem to be flavorless/neutral.This sits in my office and gets to brew 2 * 10oz cups for me daily (Onyx Geometry, Colombia/Ethiopia blend is great through this). If you only plan to brew for yourself, this machine is perfect, because if I brewed 2 cups a day through a machine with a thermal carafe or burner, that 2nd cup would be stale/lukewarm 6 hours later, I almost guarantee it (even the good Zojirushi carafes/warmers cool off after about 4-5 hours). So it's a quick, fresh cup on demand. DO NOT buy this if you plan to brew for multiple people or an office. Grab one of the bigger volume models.Have a full size Technovorm Moccamaster but made too much coffee at one time. When I was offered this one cup on Prime Day for a great price, I scooped it up although i had been concerned about the complaints that indicated it often got plugged up with grinds. It makes great coffee but I discovered that it does in fact get clogged up often. Upon investigating, I found that it most often happened when I folded the paper filters along the ridges before inserting them in the basket. When the paper filter is folded, the ridges where it is embossed tend to create small holes through which grinds can leak. Since I stopped folding the paper filters, I've not had a clog.Nothing I don’t like. This machine is equal to the full size version. We’ve had the full size version for years, but my wife is often away, and I’m tired of having sub par coffee.This machine was worth every cent. The only disappointment was not buying it sooner.Nothing touches the Technivorm.The coffee machine is very good! Makes very consistent coffee. One thing I find is that since its only pouring water from the top middle, its better if you stir it around while pouring, this allows more flavour to come out from the coffee beans.All other colours are gone from Canada so I bought the silver. Which surprising is way more stain proof than I could imagine! don't hesitate for finger prints or what not, it will not happen.Flaws:The metal tube is VERY hot, make sure you leave it for a bit before moving it around. Wish that the lid is on a swivel or something. Its quite useless if you put the lid back on while its brewing, then you will have to open it again to remove the coffee grind holder. Or this can be addressed if the coffee grind holder can be removed without removing the lid.This thing makes an excellent, consistent cup of coffee. All you have to do is bring it the right beans and it does the rest. It's a perfect solution for people who want the freshest, hottest cup of coffee every time, not that lukewarm second cup that you get with a big carafe. The only downside is the filter sometimes gets jammed, so you need to make sure it's clear before you brew.I got this for my office as I have a full-size Moccamaster at home. The quality and taste of the coffee made with the Cup One is just as good as the regular sized machine. It consistently brews a cup in just over four minutes. I have had multiple other one cup machines that use pods or discs and none can produce coffee to the caliber of the Cup One.This coffer maker does make good coffee,however for the amount of money I spent on it the cone keeps plugging up and I have to dump out my coffee almost evertime. The little tiny brush that came with the machine for cleaning only lasted about a month.i rinse out the cone after every use and before I use it to be sure I have flow but it still plugs up I didn't keep my box but you can bet I'll never order from this company again. Poor product should have gotten more for the amount I paid. Very very unhappy
