This is a good product overall, but there is a disconnect on expectations, primarily through the 12 hour claim, and a few minor annoyances. I have overcome some of its limitations through little hacks I read in other comments, and I am very satisfied as a result. For context, I have owned both the Chemex pourover and the Bodum double-walled pourover, and part of why I purchased this product relates to issues I had with those. The Chemex offered no heat retention and, as an all-glass product, inevitably had a finite lifetime in my household. The Bodum had better heat retention, but again, after losing two to breakage, we just needed another solution. For more context, my general routine is to brew and immediately transfer to a thermos mug to take to work on weekdays. On weekends, I will brew a bigger pot for my wife and I, and we usually finish off the pot within a couple hours. As a result, our demands on the product for prolonged heat retention are not high. Now that you awkardly know more about me than I know about you, let's get to specifics about the product.

Positives:
- wide bottom makes tipping very unlikely, so even though the funnel is glass, I am not as worried about its longevity
- construction with steel and glass limits prolonged exposure to plastics (depending on how you feel about that) and feels solid
- vacuum insulation keeps coffee warmer longer than single-walled brewers; coffee remains satisfyingly warm at 2 hours
- easy to poor when glass funnel attached
- looks nice on the counter
- metal filter works well on its own, although due to issues I have had with eventual clogging with sediment and oils with other fine metal filters, I still tend to use #4 filters in it - a simple well placed crease allows the filter paper to sit nicely flush in the metal filter

Negatives:
- I have not engaged in full-on testing the claims myself, but based on other reviews, but it seems like you have to jump through a lot of hoops (preheating, filling it up as much as possible) to get anywhere close to this 12 hour claim of keeping coffee hot; to be fair, I have zero need for coffee I brew in this pot to be warm 12 hours later, so I don't see myself breaking out the lab journal any time soon to run my own tests
- glass funnel tapered lip is not drip-proof (really, more like drip-encouraging), so I usually end up pouring off the side away from the taper
- if you screw off the funnel and use the cap, I can see how anyone with remotely smallish hands would have difficulty handling the base - it is simply not designed for gripping; because I find it easier to just poor with the funnel attached (despite drip-drama above), I purchased a silicone stopper used on Chemex and other pourovers for improve heat retention without the cap - easy solution that is annoying in that it requires you to buy something in addition to fully functionalize
- if you dissemble the funnel from the base (either for cleaning or to use the cap), there is a good chance you will experience a leak at the connection point the next time you pour after a brew; I think this is part heat-related expansion and maybe part limited ability to tighten down on a dry gasket; a simple firm twist when you notice it resolves the problem, but it is easy to wonder why you should have to do this, when other companies have clearly figured out how to achieve a good seal the first time

Bottom line, there are some minor annoyances, but the product is fundamentally a purchase that I can recommend, especially if your coffee habits are similar to mine. Hopefully, the company takes some of the frequently repeated criticisms in the comments to iterate on their design, because I think their product addresses a poorly filled niche in the pourover market.

I bought this because my husband has one that I love, but he drinks regular coffee and I drink decaf...or Costa Rican! Anyway, it does a great job of keeping coffee hot for an extended period compared to many thermoses I've used. Two complaints: Delivery was delayed by two days and I ordered the pink & blue marble, but received the solid pink one. It's not worth exchanging because I still love it, but they need to iron out some of their practices to get it right. Maybe this was an anomaly. The product itself is a 5 STAR. The delay and wrong color took it to a 4 STAR.

I've broken about 3 glass pour overs so far in the last year. Decided to step it up and get something a little more durable. Live the fact that the stainless is durable. The glass upper screws in easy and is easy to clean. The stainless filter has kept my cup without grounds so far.

The carafe is great, keeps your coffee warm.. the capacity is a bit small. Doesn't make a lot of coffee at one time.
The biggest issue I have, is the filter, I've had this for a few months, and the bottom of the filter came out when I was cleaning it and it won't go back in. So it render it useless. I can't get a hold of the manufacturer or the seller. So yea disappointed.

This is actually a pretty good coffee pour over. Only issue I have with it, it's the seal that is in between the pot and the pour over section. The seal tolerance's are around 1.5mm to small. I had used my calipers to measure the tolerances between the seal and the lower and upper portion of the pour over seal just seams too small. But other than that, it's great over other than leaks because of the tolerances on the seal.
