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.

I was worried about purchasing due to the price but I definitely do not regret my purchase!
I got the ceramic reusable bottle and of a morning I put ice and water in at around 7:30am, by 12:30 the ice is still partly frozen and my water stays cold all day! Any other drink bottle I have used the ice melts quickly and my drinks warm pretty fast and I will only drink cold water. I also purchased more as Christmas presents because I am so impressed. It doesn't leak, is easy to sip from and easy to clean. 100% recommend.

Honestly it is probably the best coffee cup I have found to date! Keeps it warm, easy to use and nice to sip from. They have really done a great job with this cup. Just to add as well their customer service is so amazing!!! I had an issue happen with one of my orders and they solved the probably so efficiently and with wonderful customer service! Has been a pleasant experience.

I purchased the ceramic steel cup, with monogram for 4 letters and a tea strainer.

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.

Just all too hard. Do yourself a favor and buy a keep cup, joco, or Sol cup. This cup looks great but just isn't as functional as others. I pulled it apart to clean it and it took me 10 minutes to reassemble it.

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.

It is a pain to clean, and you have to remove 5 working parts to clean it properly.
It does not seal like it claims too, and leaks badly.
Way overpriced and under delivers. The claims on keeping the coffee hot are way over exaggerated too.

AVOID!

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!

I have this frank green bottle for a year now and been leaking few weeks after my purchase; email them and they send a replacement kit to fix the issue and not even a year it leaks again. Used it for my child hot water for milk and it always leak inside the diaper bag.

I initially purchased a 740ml water bottle after it was recommended by a colleague and absolutely love it - no leaks, great size and easy to clean. I then purchased 2 of the medium sized travel mugs. I was a little nervous after reading the reviews about leaks, but I have to say mine have been nothing but fabulous. I had one leak once, and that was because I overfilled the mug. The lid has been easy to clean and I am in love with the colours. I highly recommend these products.

Bought this mug to save money on buying coffees out and so far it’s been great. I have the middle size 10oz mug in ceramic which is great but wish it was a bit bigger without needing the 20oz which is a bit big.
Coffee stays HOT for hours which is perfect for the car ride to work to still have a hot coffee.
The lid is plastic which does get quite hot though so be careful when drinking.

I love my Frank Green cup with a chip so I don’t have to carry money out when I get my coffee .
Lots of criticism from people about leaking - you have to watch the tutorial and make sure the lid is fitted correctly. Needs washing regularly but who doesn’t !

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!

The pop lid design never works first go. The complex system of the pop lid collects coffee and milk and goes rancid, even with washing. After taking the lid apart to try and clean the disgusting lid, it won’t go back together.
Don’t wait your money.

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.
