Frank Green Ceramic Reusable Cup with Push Button Lid, 10 oz Capacity, Deep Ocean

Very well insulated and just the right size! I really like the button on top that seals and unseals the mug.

The Frank Green Ceramic Bottle/Mug is a high-quality travel companion for all coffee/tea lovers.I had an opportunity to test it on short trips ( 1-4h across London ), and on a longer journey to Cotswolds.Due to the size of the product, I will be calling it a mug, rather than a "bottle", as this sounds more appropriate. It's a perfect size to replace your non-insulated travel mug on the way to work, school, Holliday trips, and so on.The design is neat and simple, without any parts that could be caught and potentially broken, had you decided to just pop it in your backpack or a duffle bag, amongst other things.It also fits very well in a standard cup holder in the car,What I found outstanding, was how long my tea stayed warm during my trip to Bourton-on-the-Water in Cotswolds. I filled up the mug fully and left it inside my car. I drank a little bit upon arrival( around 2h drive ), then left the rest where it was. The lid became quite warm at this point so I was afraid the tea would be cold. But after a few hours in the Birdland, I returned to my car to drink some more... and the tea was still warm ;) Not hot of course, but pleasantly warm to drink. So the insulation has to be made very well, to keep the liquid warm for so long in a small container like this one.I also like the idea of the push button - it is simple and effective. Easy to operate using one hand.The "drinking hole" was something I was afraid of at the beginning. Especially that for some reason I have not tried it before hitting my car to drive to the airport... It turned out to be very ergonomic and easy to drink from.My overall impression of the product is very good and upon closer inspection, I could understand what is behind the higher-than-average price(£25 at the time of this review ). The Frank Green thermal mug is made exceptionally well, with high attention to detail. All works as expected( or even better ), and the product makes an impression as it would last for a very long time.Great design and manufacturing made a truly desirable product.

Looks great and it’s a good price for a ceramic coated travel mug. Most will overlook this but the ceramic coating means you can have a cup of tea and it not taste weird like most travel mugs. It’s a better drink on the go when driving than the fellow option which is much more expensive (I have both)Only other gripe is no rubber ring on the bottom so normal use for a month has battered the coating.Tough rating but my process -+Tea tastes great+Looks great+One hand driving use- average at best temperature holding (considering it’s triple walled)-no rubber leading to a battered bottom ring….-lid mechanism is flimsy

I love the look and proportions of this cup. It's smaller than the more usual insulated cup, while a little more expensive. The design features account for this. I particultly like the entirely flush top and the gentle, mirrored curves of the top and bottom edges.

On first look at this, I wasn't expecting this to work as well as it does. The walls seem far too thin to insulate effectively, but I was very wrong. I've been working outdoors in all this hot summer weather and had a cold drink with ice cubes in this thing and without thinking, I left it exposed to full sun. The outer casing was hot to the touch when I picked it up but the drink inside was still ice-cold, and the ice cubes were still rattling about. Very impressive.In use, there is a big button on the top of the lid. Press it, and it clicks in and a small drinking hole opens. There is a vent so that the liquid flows out nicely with no glugging, and you can pour out of it too. If you take the lid off you can comfortably drink out of it as a normal cup if you prefer. Press the button again, and the little hole closes and everything becomes water tight again. Easy.One concern to me was the complex button mechanism would be a nightmare to clean and a horrible bacteria trap. And it is, but a nice touch is that you can easily take to pieces. Unscrew a little knob on the inside and the whole thing breaks down into pieces so you can really clean it properly when you need to. It's a bit fiddly to put it back together again but not too difficult, but it's worth it to have the ability to properly clean.Build quality is excellent and it shrugs off being dropped. The lid and the body are both metal so it will survive scratching and bashing about with nothing more than a few dents here and there. It's cup-sized so will fit into standard car cup holders and is easy to grip and comfortable in the hand.The only downside for me is the small capacity. It only holds about 300ml, which is frustratingly just too small to hold a cans worth of drink, and too small for most store-bought coffee amounts. It handles fizzy drink ok, but you need to unscrew the lid slightly to relieve pressure if you've been shaking it about or the button won't work. No big deal.It's a very expensive cup, no doubt, but it works. I'm pretty pleased with it, but I just wish it had slightly more volume.
