Green Green #1481

I'm only rating this mug 2 stars because the first time I ordered it, it didn't work. It says to flex the rubber on the bottom but everything I did it didn't stick to any of the surfaces I tried. Figured it was somehow not attached correctly so sent it back. It was a Christmas gift for my dad so I decided to order another one.. The second one worked like it was supposed to. My biggest complaint is that the top black part that has the handle isn't secure and moves a little bit. My dad like it's because it's a decent size for his coffee and he doesn't have to worry about it being knocked over. Also $40 is an outrageous price for such cheap feeling plastic with a loose handle on it.

People place this on my countertop and stand there and punch it, trying to make it tip over. Then they lift it straight up and it releases instantly. Then they laugh like crazy. It draws a crowd. Not only is it a cool product, but I'd bet that if you either had children around the house, or could be a bit of a klutz, like me, this would be essential equipment.

I brought this mug as a Christmas gift and after washing it, the mug would not stick to anything anymore

Love this mug! I bought this mug for a friend if mine for Christmas and he LOVES it! This absolutely does not spill! I have two of my own, if I can just find the box they're in since I moved.

Doesn’t tip over. Just as advertised

Cool! It won't tip over. Keep the bottom clean, the cup creates a vacum to"stick" to the counter. It may not stick to rough or dirty surfaces.

Sent it back, it would not stick to any surface.

あくまでも写真を見ただけの購入なので色や大きさは把握できないのですが、色はがっかりしました。2回くらいは触れても倒れなかったのですが後は全く普通のカップと変わりません。これでこんなに高いの？残念です。

倒れないとのコメント。半信半疑で購入しましたが、本当に倒れなかった。使いやすいのでお友達のプレゼントにもしました。

大きさの割に軽く、倒れにくく、保温機能も満足のいくものでした。オフィスデスク用として重宝しています。

押しても引いても倒れないのに感動。でも飲むときにはすっと持ち上げられる。保温保冷もできるし、蓋付きなのも良し（半透明だったりすれば中の様子が見えていいときもあるかな）。
