Ex Input:
Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level.  Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.

Great product, nice combination of chocolates and perfect size!  The bags had plenty, and they were shipped promptly.  The kids in the neighborhood liked our candies!

Bought a set of two when my son was about 6 months, and we started taking them with us whenever we went out to eat.  I cut up cantaloupe, apple, banana (even used sweet potatoes a few times)-- just whatever I could get at the restaurant-- and it would keep my son busy long enough that I could actually eat!  It's great because I didn't have to be overly worried about him choking on big chunks, and he got to try out new foods.  I wouldn't hesitate to buy this again.
