I absolutely love this awesome cup which I can chuck into my bag without worrying about the leakage. It is quite pricey, but I found it worth that money. You can't easily get it from everywhere, this is the one for you if you like something unique and has beautiful design/ feature.

I purchased a frank green cup recently as I wanted a permanent coffee cup that does not spill. Within the first use of the cup, it leaked coffee in my bag which damaged my laptop n stained my bag. Really disappointing as I purchased the cup for a premium price. Now I just use the cup as a toothbursh holder

I purchased a Frank Green coffee cup as a gift because after scouring the internet for suggestions, it came up quite frequently as the one to buy. I'm not sure how this is the case, because once you get past the beautiful aesthetics and the premium feel of the product in your hand, it just sucks.

The lid is over-engineered and impractical and the little sippy hole just makes drinking coffee truly unenjoyable... That's if you don't burn your lip first.

I really, really wanted this to be as good a product as all the vloggers say it is, but as you can see from mine and everyone else's reviews, it's not.

Paid $50 for a new drink bottle. It's stylish and an eco friendly company. BUT... the button Lid is faulty and unreliable. It works and then I doesn't, and sometimes I'm stuck pushing the button 10 times before it opens or closes. For the money spent, the quality isn't there.

As other reviewers have said, the paint on outside of these just strips off so quickly. It’s really bad.
Cup itself works well in terms of coffee (or a cheeky G&T) but there are definitely too many moving parts in the kid that milk and other liquids get stuck in, difficult to wash out making it stink and terribly hygienic.
Paint job probably the most disappointing part.

looks great, feels nice, easy to drink from and doesn’t leak but omg so ridiculously hard to get clean, totally over engineered, too many parts, i have 3, 2 were gifts, so it means i have spare parts, would not recommend or repurchase

Received Frank Green reusable coffee cup as a gift from work. Design looks absolutely beautiful and seems to insulate hot drinks well enough. However, the biggest drawback for me and the reason I would not buy it is that it takes a lot of effort to clean. Coffee (or any liquid for that matter) gets inside the opening and closing mechanism and requires disassembly of around 5 different pieces (try figuring out how to reassemble it back the first time!). Some small corners are impossibly hard to clean unless you have a thin pipe brush, similar to what you'd use for cleaning baby bottles and even that is some work in itself. Food and drink containers should not be this difficult to clean (even with instructions).

I was given this cup as a present and made a hot drink in it to take to work.
The cup was instantly too hot to hold and by the time I got to work, about 30mins, the drink was cold, what a waste of money.

Has leaked from day one. No combination of pressing the little button up or down changes the fact that it leaks no matter what. Lovely colours and appearance but there has to be a design flaw if so many people have the same issue.

This is such a great reusable coffee cup! I love that I can chuck it in my bag without it spilling and it is a nice compact size. Would definitely recommend giving them a go!

This is not the perfect cup - could keep hot drinks hotter for longer and it is a little clumsy to clean but I still love it - love the shape, the size and way it feel and the opening (better than the Keep Cup I used to have) and haven't had any design issues, only if I haven't closed it properly and I totally own those moments. I do not understand any of the negative issues people have had I can only think they didn't know how to use it properly - its not rocket science, but I cared enough to look up the care instructions. I would advise everyone to do that and not be lazy or ignorant. And you'll have no issues.

I was gifted two Frank Green original resuable cup (small). Used it for a cup of hot coffee, and within minutes, the outside of the cup became way too hot to hold (push button was in the open position to let the steam out). That is quite unexpected for a double-walled insulated cup. I thought it might have been a lemon, so I tested the second cup. It was the same result. What good is a double-walled insulated cup if it's too hot to hold? It also means that the insulation is not that good.

Do not buy anything from Frank Green. The product is low quality, leaks like everyone says and is NOT dishwasher safe! The lid no longer twists on and the whole cup is now garbage and I've only been using it for a month! Wasted hard earned money on two of these!

It leaks so much that its actually ridiculous. For the price I paid for this, I feel ripped off. I'm suprised the company has not done anything to address this!

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 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?

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
