Ordered a sampler pack to test modafinil brands

So I ordered a sampler pack that had a few of the main brands, Modalert, Waklert, Modvigil, and Artvigil. Out of all of these types of modafinil, Modalert was the best all-round but Waklert was the most effective to me. I'm glad I only spent a little bit on a sample now I know where to concentrate my money for the next purchase. I was expecting my order faster, but what can I do about it? I will return here 100%.
