Happy Shoppping | Biggie Tumbler, Coffee, Thermos Vacuum Bottle Water Cup Travel Mug/Flask with Osculum | Plastic , Black, 18 oz

It really works! As long as it is sitting on a clean smooth surface it won’t fall over! Tried it on glass,wood,tile and plastic. Only downfall is if any dirt/crumbs get on the bottom of cup it won’t seal, so it will fall over.

The "never falls" is amazing you can hit it really strong and it will stay steady, but it leaks through the top. If you are planning to only have this in your desk it's perfect, but if you are going to be carrying it in your bag, don't get it, it will spill all over your things.

Love that it does not tip. It does not however keep things hot or cold for very long.

I bought the mug specifically because it was plastic. I read so many reviews about how great it was. I have had it leak on me several times and my coffee went cold within an hour. I was bummed.

This is perfect for the clumsy person who spills their drinks often. Have had it for almost a year, use it every day in the office and still no spills or any issues. Highly recommended it

Best cup ever. I need this to stop from knocking over my cup at work. Really works greatI extremely happy 😃

It really does not fall over. Just as advertised.

Can't rate it with zero star, do not waste your money, will not keep coffee hot for more than 15 minutes.
