VERIFIED OPINION
SMART CAFFEINE
Great
I think they are great, I take them because I needed a "little boost" for the afternoons. I usually felt very tired and had a hard time concentrating. I take one after lunch and it's great until the evening. They don't make you nervous or anxious as you might get when you drink a lot of coffee. I think they are simply great!

Works very well
I notice that I am more active and focused for longer. Without that spike and crash of other caffeines.
