I keep looking for a travel cup or sports bottle that I can drink from while traveling and use while I am at work.
I have tried several different kinds from Walmart but they always end up leaking. The other day while I was there I saw what look like a promising travel mug. It cost two or three times more that what I had been spending on these travel mugs/sports bottles which was usualy $1.00 cents to $2.50. I thought the higher price meant it would be a better cup. I got the 16 ounce soft grip blue tumbler. It's a plastic cup that is coated in a blue rubber case. The rubber grip makes it easier to hold onto. It even had a sliding piece that covers the hole you drink out of in case you knock it over or it falls out of the cupholder.
The problem with this tumbler is that it leaks and the lid barely slides into place which makes leaking and spilling easy. I guess higher price does not necessarily mean a better product. It's time to look elsewhere for a good travel cup/sports bottle.
