There are so many types of Tumblers on the market, you never know which ones are worth the investment or just plain old junk. Everyone knows you can spend a ton of money on a "good" Tumbler. Sadly, these companies are great at marketing but the same quality can be found at a much cheaper, like half the price.
I took a chance on the Ohero Viva because of a couple features they have. I didn't know much about the brand itself or if it would worth the space in my cabinet. So, let's see good or bad it turned out to be.
