I love these glassware and mugs. You gotta lift straight up. I love it. I'm pretty clumsy sometimes and smacked my mug a good couple two, three times. Mug never tipped. Love it so much, I bought one for my son. He loves it too!

Love the Mighty Muugs. Gave them out for Christmas presents.

Received many compliments on these cups and nicely made. Highly recommended!

Great product. Great experience all the way around! Order came in a timely manner!

My second mug. Love it and only use it each morning for my caffeine fix. Would recommend it to anyone who wants a sturdy mug, that retains the proper temperature for you to enjoy your drink, wants something that resists spillage, and is hilarious to use when you ask someone to bring your mug to them without first warning them of the abilities of the mug. Great invention.
