I haven't tried the cup yet, so maybe it's a great cup, maybe not.

Just want others buyers looking for a ceramic cup to know that it is a silicone based ceramic (Frank Green support told me this when I complained the internal layer wasn't ceramic). So it doesn't have the same feel or look as a clay/earthen glazed coffee cup at home. It is still ceramic, but silicone based.

It seems easy to find a nice ceramic glazed cup with a silicone lid. I was hoping this was the solution for a screw top lid. I have little kids who accidentally knock things over.

Unfortunately when I received it, it wasn't perfect with a small scratch on the base. I emailed customer service with a photo and the next business day I got a reply to say a replacement base is on its way in Express post! Got it in the mail a few days later and they had upgraded me to the next generation base! Great cup, no leaks, looks great and practical.

The cup leaks like an uncontainable waterfall. It surprises me how much more liquid leaks as i hold it up right, when trying to wipe off the original leak. This product is definitely not worth your money. considering it’s price, you can get much better product than this.

For something that costs as much as it does, this cup leaks all over the place. I thought it didn't have a seal inside the lid but it does so the fact it leaks is baffling. Awkward to sip from as well, and sometimes will just bubble your drink on to your nose from the 2nd air hole. Main cup is fine to wash but the lid takes on a lot of water and you either have to unscrew it all to dry or stand over the sink for a while shaking out water.

Doesn't really have a thermos function.

Never used the tap and pay function because I have a phone so why would I?

Looks good, that's it.

I bought the original cup (polymer) and then more recently the stainless steel cup. Honestly, I wouldn’t waste my money on Frank Green. They are overpriced with many design flaws. There are many other better products out there to pick from. The lid design was not very well thought out for function. It looks good on the shelf but that’s about it. The design process is too try hard to be sophisticated. I thought I’d give them a second chance when I bought the stainless steel but even after 3 years they have made no changes in product improvement. It is definitely not leak-proof so im not sure how they got away with claiming that...

I love this design, it's the only reusable coffee cup I can get a coffee in and throw in my handbag knowing it won't leak. Perfect for a mum with kids and 6 bags to carry. The coffee / tea also stays warm for a long time as it's sealed.

The downside is that although it doesn't leak when you keep it relatively upright in a handbag, after 12 months of use it leaks as soon as you tip it up to take a sip. I've disassembled and reassembled the lid & screwed the lid on super tight but nothing works. It's now useless.

Very disappointing for a product that you purchase to be more sustainable. Apparently they are made from recyclable materials, but who knows where it'll end up if you throw it in your recycling bin?

Please do yourself a favour and read the reviews before purchasing this cup. Leaky, leaky leaky! The company knows there are problems but they act like it's somehow your fault. For a company who claims to have a sustainability imagine, their customer service is atrocious. They receive so many negative reviews and yet do nothing to solve the problem other them tell you to dissemble a brand new cup and reassemble it to try and stop the leaks. I wouldn't even pay $5 for this let alone $30.

Frank Green refused to provide a refund and they actually stopped replying to messages. Don't waste your money on these cups, they look good but that's about it! Poor company.

Worked OK for the first 6-12 months with only occasional small leaks but now consistently leaks all over the place. The push button mechanism it quite complicated with lots of places for milk and coffee to get lodged and then REALLY smells after a while as its hard to clean. We also paid extra for the stainless steel cups after initially buying the original - did not make a single bit of difference to heat retention and was luke warm after an hour. I honestly dont know how these are still sold everywhere when they're SO BAD

I have three of these cups the original, next gen and Stainless steel and I love them all. I love that they can just be chucked in my bag when I'm finished and they never leak. I love the texture of the Original and Next Gen cups and I love the thermal ability of the Stainless steel, my coffee was still hot an hour later, the only thing I would change in the stainless is the texture I prefer the Co-polymer casing for the non slip.
You do need to watch the lid assembly tutorial to get it right. I don't use the tap feature so can't comment on that but love the cups.

My Frank Green stainless steel cup has always leaked from the moment I bought it, and yes, I am putting the lid together correctly. I have it filled well below the "max fill" line and it still leaks. For the price it is terrible quality. I will never buy Frank Green again.
The store I bought it from, The Clean Collective, suggested I wasn't putting the lid on right.... It's not that complicated.
I stuck with it because it was so expensive, it seemed wasteful to replace it but after several months I can't put up with it anymore. Also, I have only ever hand washed it and the coloured coating is coming off all over, it looks awful.

Rating it a 2 because after 5 months of use, the cup is starting to show wear and tear. You cannot put this in the dishwasher. I love the design and the colors but this product is not durable. I contacted Frank Green for a replacement and got a "no". You would expect an expensive product like this would last further than 5 months. Very very disappointed with Frank Green. Would NOT recommend this to anyone.

Bought it for2, no experiences on its usage quality yet, will update later.

first impressions on these products is ZERO. Poor finished look. The connection btw lid and cup is worse, push button required hard force than I think. The colors tone is bit different from the website.

Overall not worth for my money.

The lid on my cup is really difficult to screw on and most baristas give up as it takes too long to do. The cup leaks badly and I have ended up with coffee all over my clothes on several occasions. I also find the hole at the top uncomfortable to drink out of and coffee always drips over the top after drinking from it.

I bought this to use for school and it worked great for 1 month before liquid started leaking out of the air hole. I emailed them and they replaced the inner lid parts for free, so the problem was resolved...but then it started leaking again only 2 weeks later. While it does keep your liquids hot or cold for hours, the leaking is greatly disappointing as its the reason I bought this over other travel mugs. Its frustrating that this is an issue for a product that is quite expensive and preaches about being "well-designed, stylish, and really convenient." A leaky cup is neither well-designed nor convenient.

Like many others - this cup leaks from the seal after only a couple of months of use.
It would appear the material selected for the cup lid is too soft to use in a coffee cup and deforms/shaves away with constant removal and replacement of the lid.
I reached out to frank green to ask for a replacement lid - rather than just send one out - they wanted photos, then wanted proof of purchase and where I got the cup from.
Nobody else makes frank green cups - I'm not trying to trick you by asking for a replacement lid.
The company obviously doesn't care about customers or the environment.
Do not waste your money on this overpriced landfill.

Not a bad cup but so many pieces it’s really hard to put back together after cleaning - and is virtually impossible to clean properly especially when drinking almond milk based drinks. I see these tiny fiddly pieces going missing very soon too.

Mine doesn't leak at all, as long as the lid is screwed on firmly. So it is functional.
However it's hard to clean, as the lid assembly has nooks and edges, so you can only clean it so much day-to-day, and you'll have to disassemble it from time to time do give it a proper clean. Even then it's difficult to get it completely clean.
The cup also retains a coffee and dishwashing liquid odour even after drying. Maybe it's just the nature of plastic.
While it is durable, the exterior is prone to staining. Mine is in great condition, but it does have a light stain on the outside which doesn't wash off.
