Good Design - Needs a Better Carafe
580192
This coffee maker has a design that makes it easy to fill with water without spilling any. This is due to the large reservoir and opening to the left top where the water goes. The percolator action is a bit slow but the quality of the finished coffee is good. My biggest complaint is the so-called "thermal" carafe. It has virtually no insulation and the brewed coffee will not stay warm for more than a few minutes. So if you plan to brew and immediately drink the coffee, it is fine. But if you leave any coffee in the carafe, it will get cold in a hurry. One other minor complaint is that there is not brew shutoff valve so you have to be careful that all the water has finished passing through the grounds before you remove the carafe.

There's no doubt this design is the economical version of the infamous Technivorm. As a result it brews a nicely balanced cup of coffee. Unfortunately the design suffers some major flaws.

The most major flaw is that the filter basket sits on top of the carafe instead of latching onto the machine's body. What this means is when your coffee finishes brewing you need to remove both the carafe and basket together. If you are inpatient you'll find there's still water seeping in the basket and, with an unsteady hand, may risk spilling grounds down into the carafe. Quickly you also realize there is no shutoff valve to stop fluid from draining into the carafe. If you happen to wait long enough after the machine's light turns off for the coffee to fully seep, then you need to discard the filter and place it's basket in a sink for cleaning (no, this is not dishwasher safe). Finally you take a separate lid and attach it to the top of the carafe. If you've made it this far, congratulations! You can now grab your favorite mug and enjoy a cup of well brewed coffee.

After enjoying your beverage you'll have 3 components that need to be hand washed before your next brew (the carafe, screw on lid and filter basket). Lastly this is not a programable coffee maker, which means you'll have to repeat all these steps from scratch the next morning.

Overall I recommend this coffee maker for the enthusiast that demands a great cup of drip coffee and doesn't mind a cumbersome brewing and pouring experience.

I ordered this coffee maker as a replacement to a basic Mr. Coffee coffeemaker. It has pros and cons.

The Pros:
 The coffee tastes great!
 The carafe is well-insulated and keeps the coffee hot even though the maker doesnt have a warming plate in the base.
 The coffee maker can be programmed remotely using a smart phone and the WeMo application.
 The removable water reservoir is convenient in that it can be removed, filled with water, and then snapped back into place in the coffeemaker.
 The coffee maker is attractive.
The Cons:
 The carafe holds 10 5-oz cups which is insufficient for our familys needs.
 The basket where the coffee is added is inconvenient compared to the previous models Ive used. In addition, the filter disk often pops out and ends up in the coffee grounds
 The programming doesnt always work and the coffee maker sometimes has to be started manually.
 The WeMo app is not the most user friendly.
Bottom line: The Mr. Coffee Smart Wifi-Enabled WeMo 10-Cup Optimal Brew Coffeemaker makes good coffee and keeps it warm. These are probably the most important of the comments that I made below but I feel that a good coffeemaker should be more convenient to set up. The wifi programming seems like more of a gimic than a useful feature . Finally, the price seems a bit high for what we get.

I actually love zojurushi products (even bought their uber fancy rice cooker), however, I can't say the same for this coffee maker.  I purchased this due to all the great reviews posted.  I love the small space it takes up and it's a perfect size for me.  The design is flawed because of where the coffee and filter is placed.  When you remove the carafe from the machine to pour coffee, some of the grounds always end up in my coffee.  With traditional coffee makers, the filter/coffee piece remain in the machine, in this design, that part goes with the carafe.  To compensate, I have to remove the top pieces before pouring- so not a big deal, however, a little annoying that I have to do this extra step for such an expensive machine.  Also, my carafe is now cracked and it has been through normal use.

The coffee maker makes a great cup of coffee but you'll notice a consistent theme in the reviews - the main problem being the carafe. (Replacement carafes cost $5 more than replacing the entire coffee maker!)

Over the past 15 years (we really like the coffee maker!) we have gone through three of these carafes - only to have them fail or break. They dribble coffee - have a cheap plastic hinge, and are the most fragile item we have to wash in our sink every day. As some reviews state, you just have to be careful - but then most of us are usually half asleep when we make our coffee.

After the plastic drip stop mechanism on the coffee maker broke, we recently upgraded to the KF600. It has a sturdy metal thermal carafe and makes the same great cup of coffee. Paying a few extra bucks should prevent us from replacing anymore carafes.

Makes a very nice pot of coffee and I do enjoy being able to vary the brewing strength, BUT if you have the misfortune of breaking the carafe you are going to have to jump in and out of a few hoops to find a replacement.  Nowhere online could a replacement carafe (orignal manufacturer or third party) be found.  Emailed Oster but did not get a reply from them for help.  Called and they were out of replacement parts for their own product!  When I finally found a replacement at smallappliance.com by calling them (part not listed on their website) the cost/shipping was almost half of what we paid for the original coffee maker.  Further notes: a little messy pouring in the water if you are short since the unit stands rather tall.  Have to give more attention to cleaning the mechanism to prevent brewing leaks.  Yes, we'll continue using this Oster coffee maker, but will not replace it with another Oster product.

Looks great. Brews good coffee. Many features, and easy to set the delay brew feature. But the carafe has no seal, so it's not very useful in keeping the coffee hot past 90 minutes.

This coffee maker looks good and makes good coffee, however, I can't seem to pour water from the carafe into the water resevior without spilling.

Replaced a glass thermal carafe machine.  This unit makes great tasting coffee, but I find it less easy to use.  One big issue is the filter bowl.  It is too short requiring you to force a # 4 filter down into it.  It also barely accepts the needed amount of coffee grinds for strong coffee (5 scoops) and it does not keep coffee hot for more than about an hour, due to the aluminum carafe.  Aluminum can never hold heat as well as glass.
All in all, we went back to the old Krups brewer.  If taste is the higher priority, this is definitely the brewer to buy.

Let me start by saying I do love the coffee that is brewed by this coffee maker, and I love the fact that it can be calibrated for altitude, and temperature can be adjusted. I repeat, it makes a great cup of coffee.
The problem I have is with the Carafe. I've had this coffee maker for a year, and the carafe has never kept coffee hot. I might point out for anyone who is unclear on this that THIS CARAFE IS NOT VACUUM INSULATED. Anyway, I get one good cup, then have to microwave every subsequent cup. I figured I just got a bad carafe, since many reviewers state that  theirs keeps coffee hot for hours. I still believe I may have a bad carafe. I finally got around to contacting customer support about this problem, stating that my carafe will not keep coffee hot longer that about a half hour. I am even willing to purchase a replacement, if mine has an issue, but that doesn't seem to be the recommendation of customer support. I was told that SCAA certification only requires that the carafe maintain temperature for 30 minutes. Basically, the emails (there have been 2 replies so far) seem to be saying tough luck, we meet the minimum requirement, so we don't care. Based on this, I will buy my next coffee maker from someone else.

The carafe is just ok.  The lid is one of those where you have to exactly get it right to screw on properly, otherwise it doesn't seat all the way.  It pours very slowly, so that is not so great either.  It does keep the coffee hot for quite a while and we still use it, just not super.

Could be improved. After using this coffee machine for a couple of months, I would make some changes. First, it is awkward to pour the water in the pot. No matter how you do it, it's awkward. Also, I would make it easier to read the numbers of cups on the carafe. Make the numbers larger and darker. it's annoying to take carafe out from under water spout to see if amount is correct.
I had to use the coffeemaker for a week before got true coffee flavor. Now, I like it. Some features I like: the coffee comes out hot, and the timer is a nice feature. I also needed the color white for my kitchen.

Update:  After a few months of use the leaking that others have reported began to show up.  There is ALWAYS leaking to some degree after making a pot of coffee which means coffee pools beneath and around the coffee maker.  As was the case this morning, there are occasions when it is as if an entire mug of coffee was poured on the counter.  I can no long recommend the purchase of this product.
____________________________________

Pros: (1) Convenience and safety associated with no carafe, (2) 2-hour auto shut off, (3) easy-to-use programmable timer to have coffee waiting for you in the morning, (4) looks nice, (5) price.

Cons: (1) Inconvenience of no carafe as refreshing cups at the table requires dispensing coffee (rather slowly) into an insulated carafe, (2) water level marking hard to read in the tank, (3) coffee level hard to read as the front window of the tank retains condensation and makes it appear that no coffee has been dispensed even when empty.

Wish: (1) As to that last point above, I understand it would void the warranty, but I am exploring the possibility of making a ball float and cage that could be epoxied into place on the back side of that window to make the coffee level readable.  Any less obtrusive suggestions would be welcomed.  (2) The ability to adjust the automatic shut off time would be nice. (3) A channel to direct the coffee flow so it would be dispensed more toward the center of the cup would be nice, but so far has not been a big deal.

you need a lot of counter space for this.  The carafe is really nice design, and pours nicely.

Makes a great cup of coffee BUT has some serious shortcomings.  Minimalist European design dictates that this coffee maker makes you REMOVE the carafe WITH the filter unit THEN carefully screw on the top for serving.  Making this unit a a whole lot simpler would have added about 2 inches to it's height.  Also, glass thermal carafe works really well until it shatters during routine cleaning.

Looks pretty and takes up little space, great cup of coffee. BUT the carafe drips where the stainless steel band is on the carafe.  It drips A LOT.  On every single pour.  So I don't recommend this because I presume it's a design defect.

Once you know to measure 10g of medium/coarse grind to 5 oz of water, this coffee maker brews a very good pot of joe. The no frills, one-button design are standouts to its simplicity and ease of use. However, the product is not without some design flaws. The machine is designed so the filter rests above the carafe. When your coffee finishes brewing you need to remove the filter to screw the spout onto the carafe. The more time you take to do this, the more you risk in heat escaping from the carafe. It's not a huge deal, but my old routine was to start brewing a pot of coffee, walk the dog and come back to a fresh hot pot. Now I start brewing after the dog's been walked. My other pet peeve is the design of the thermal carafe. The enclosure/handle is designed with two much of an overhang, essentially trapping about an ounce of coffee in the pot. It's not a full cup of coffee being left behind, really only about an ounce or two. But it is kind of annoying.
