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.

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

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.

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.

- 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.

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!

I actually used to have the Original Frank Green cup which I found leaked when I used it for Tea. I think maybe it was the boiling water being poured in it that might have caused the leak (who knows). Anyhow i thought i'd try the Stainless Steel one. I thought - less chance of boiling water warping the cup to cause leaks. Well so far its been pretty good. Keeps hot drinks hot for awhile. The lid is spill resistant (as advised by Frank Green). The button which controls the flow of coffee/tea/water gets a little sticky so i need to press it a few times to get it to open or close. But this is not too bad. The cup looks great - pretty high end looking! Fits into my car cup holders well. So far so good.
