I love my Gladiator! Luckily there is a Smoothie King near my office. If you join their VIP club ($15 per year), you get a % off products every day and on Sundays, if you buy one you get one smoothie FREE! And if you don't need 2, they give you a freebie card for another visit. It is an awesome deal. I have only had the strawberry/banana; but I'm going to try the blueberry also.
The small is a lot, it usually takes me about 45 minutes to drink one. But it is sooo worth it. Great protein for not alot of calories or carbs.
