I have been a long time keep cup user but found the coffee to go cold too quick, the stainless Frank Green cup is like a thermo flask and stays hot for ages. Mine seals perfectly. I was dubious after reading some reviews but glad I decided to give it a go.

I bought this bottle for my Mum for her birthday. It started leaking within a couple of days. Despite me requesting a refund or replacement from Frank Green, they continually refused to do this and instead sent me spare parts, requiring me to manually fix the lid myself following instructions on a video. Despite doing this twice, the lid still leaks. Very disappointing that such an expensive product is unable to be used at all due to the leak, and that Frank Green won't take responsibility for their faulty product, putting me through a never-ending process to get the problem fixed which is no doubt intended to make me give up altogether! I have made a complaint to the ACCC.

I bought this and then read the reviews and was prepared to be disappointed but it's awesome! Keeps stuff hot for hours, doesn't leak or dribble and looks fantastic. Highly recommend

Purchased two cups for my wife and I. They both leak from the seal. Overpriced cheap rubbish. The lid is also annoying to clean and retains liquid which also leaks when drinking.

1. mug arrived leaking
2. build quality with jagged edges and uneven lines doesn't warrant the $40 + shipping pricetag
3. was quoted 7-10 working days, it arrived in 14
4. the rubbery exterior scuffs and scrapes at a worrying rate. expect your mug to look old enough to replace within a month
5. rudest, most dismissive customer support who do not want to help at all with my concerns
6. there is a noticeable plastic taste if i brew my coffee straight into the mug. i have to allow my shot to cool before pouring it into the mug, lest i want an unappealing taste of chemicals with my coffee.

such a shame as the design has potential

I bought two cups about 15 months ago.
Believing the hype about how good they were. Being leak proof. I have found them to be anything but leak proof.

For reference I have the stainless steel water bottle and use it for ice water.

This is the worst water bottle I have ever used. It constantly leaks through the lid and the paint quality is terrible. The paint started wearing off within the first few DAYS of use. I emailed frank green about it and they said it is just regular wear and tear. Sorry but a $50 bottle should not be wearing down in less than a week!

The leakage is always a big problem. Stuff in my bag always gets wet. The condensation on the lid is also crazy.

Don’t waste your money on this bottle. You’re better off getting something from Kmart for better quality and less money.

I obtained my Frank Green cup during a Sydney Westfield x Frank Green promotion and generally use it to drink coffee or tea on the go. It’s relatively light-weight compared to other travel cup options and easy to carry around.

However, like other reviews, I found that the cup/bottle tends to leak but only if the outside rim of the base and/or the inside rim of lid (i.e. the areas where the lid and base are screwed together to close the cup) is wet. Solution is to wipe down these areas with a paper towel and ensure that they are completely dry before closing the cup - not 100% foolproof but it works.

I have a large and a small one of these cups. Love the design, love the flow of coffee from the spout, but after a while I am getting coffee all over my lap which is leaking from the seal between the lid and the cup. Latte and other frothy beverages it isn't a huge problem, but more watery drinks like iced coffee and tea it leaks almost every time. I have to take a napkin with my coffee to prevent getting drips all over me.
I really wanted to love this cup but I cannot with such a design flaw- especially when it is promoted as "spill proof".

This is a nice cup, and I've bought a several for friends and family in the last 12 months. It's not cheap at all, $40 for a coffee cup. I was disappointed with the customer service when I emailed to ask them to add a code to my order which would save me the shipping cost, they refused to. One would thought being a loyal customer (this is the 6th cup I buy from them), they would have the courtesy to at least allow free shipping if I have a code, I emailed straight after. Had they allow it, I'd keep recommending and gifting it to people, but now it's just disappointing.

Loving my smart cup! I got it for myself for Christmas and it has been great ever since.
It doesn't leak and I can use it anywhere, as it is the Visa pay wave.
(not sure why the "bottle" reviews are in with the cup reviews).
I loved mine so much, I bought them for friends and family for Christmas.

- When drinking from one "hole," the beverage will leak from the other hole if the bottle is tipped too far ie. when drinking last few drops
- Significant force required to push down open/close button
- Leaks when screwing on lid if more than 3/4 full
- Rough edges and cheap, poor quality plastic on lid (cracked causing the lid to leak when dropped onto lino floor from 20cm)
- Paint on body of bottle chips off over months with normal use

It does keep water quite cold for a fairly long time.

This cup does not do anything a reusable cup shoud do...

1. Hold liquid: It leaks badly! I don't trust this cup. It has spilled all over my bag and all over my shirt when drinking on more than one occasion.
2. Be easy to clean: Coffee wil stain this cups outer material like nothing you've seen before. Stains do not come off unsless you want to spend 10' cleaning the outside of the cup every day.
3. Keep beverages reasonably hot for a while: Your coffee will be cold in a matter of minutes.
4. Reuse: You're not going to... see above.

So just don't.

I love FG cups and have several types. The water bottles are a great size and the stainless steel keeps the drink chilled or hot. Best of all my lipstick wipes off easily and doesn't stain like with other type of recyclable cups. FG doesn't leak like others do so perfect for the handbag. Its handy to use the Next Gen pay card for other purchases too. Love that I can change colours too. I like that its all Ozzie made too! Hope they bring out espresso ones soon!

My girlfriend and I purchased 2x next gen cups as gifts. Both arrived promptly however one had a manufacturing blemish. They replaced it however the replacement showed the same blemish.

My girlfriend has subsequently purchased one for herself and it also has issues. the lid and base are the same colour however different shades, there are marks I assume also from manufacturing, the lid edge is poorly finished and rough, when screwed down is also slightly askew.

They are a nice idea with the built in payment however for a premium price the quality is lacking. You would expect issues like this at half the price or less.
