REVOMAX Threadless Vacuum Insulated Water Bottle with Twist-Free Lid, Travel Insulated Thermo Flask, Iced Coffee Tumbler, Coffee Ice Cup, Keeps Hot and Cold (Silver)

I’m glad I bought this bottle, very smart design! Easy to open with one hand when driving, kept my coffee hot all day long!

Pro: love the opening design, keeps the cold cold and the hot hot. Minimalist design! Con: -500ml isn't enough for me, would need a 750ml or 1L version. -the translucent rubber seal that came inside the bottle came misplaced, so I took it out but it is quite impossible to put it back where it belongs, and there's nothing on the description of where to put it. Overall, I was using 750ml S'well for couple years and this seems like a nice bottle to switch to, however the little capacity isn't enough for me.

Leak proof, easy to use. No hassle top. Great product!

It's doesn't hold cold for 36 hours as advertised. It's a nice bottle but not so special as one might led to think. The top is nice and not really complicated once you open or close it a few times. Just disappointed in it's inability to retain cold. Filled it with ice and water for a round of golf in 90º weather and the ice was almost gone in 4 hours. Sure I opened it a number of times to take a drink and refilled it with ice cold bottled water but nothing out of the normal. My big fake Yeti cup with a plastic top (Walmart) is better!

I now have three of these, because my wife and I kept fighting over them. The flasks are super high quality and keep drinks either cold or warm for one heck of a long time. At least a day. I REALLY like the one hand opening feature, which is handy when you are driving. The caps are NOT twist off. One thing about the pure stainless model is that there is no paint to chip off. I have a couple of colored ones that started chipping after about three years of heavy use. I still use them and love them.

Great bottle. Keeps drinks cold and love the No Screw cap.

I bring a thermos of coffee to work and my new Stanley (to replace my 40+ yr old Stanley) lid spout leaks and makes a mess while pouring. I decided to try this one and so far I am pleased. I only need it to stay hot for 6-8 hrs and it does that but by 12-14 hrs it is lukewarm. I don't think it will keep hot for 18 hrs (as advertised). As with most thermoses, pre-filing with hot or boiling water helps. I took apart the lid to wash, as per instructions, but didn't put the 3 pieces back in the correct order so be sure you read the instructions and put back correctly. The silicone ring goes into the lid first, then the plunger. Works perfect. I'm not worried about it leaking in my backpack. I picked the color that cost the least and I'm glad it was silver not purple or pink.

Nice,easy to use.I like it. ☺

中が保温や保冷の兼ね合いか、少し本体の大きさに対して入れれる容量が少なく感じますが保冷、保温共にすごく優れていました！ 買って良かったので家族も欲しがって隠れて買っていましたw

アルミボディのオシャレな水筒を探していて発見 聞いたことないメーカーだったが試しに買ってみたら思ったよりデカかった笑 性能は保冷保温共に長持ちしてくれるし、キャップの開け閉めが楽しいし便利なのでおすすめします！ メーカー代理店のサイトで会員登録するとキャップ内のゴム？が無料で貰えます

蓋の開け閉めが非常に簡単で使いやすい。しかし、炭酸ガスが自動で抜けてくれないので、定期的に抜いてやらなければならないのが難点。

温かい飲み物を入れているとキャップ部分に水滴がついてしまい、開けると垂れるときがある。 象印の水筒からの買い替えですが保温力は象印のほうが高い。 車のドリンクホルダーの大きさによるが入らないときがある。 キャップの使い方にはほとんどの人が興味をもち話のネタになる。

一度、お店で実物を見た事があったので、実際に使用してみてとても開閉が楽で気に入ってます。
