"Smart Products" in the GC Shop

Hey, i was just curious if any of you have ever tried any of the "Smart products" as seen here: http://shop.grasscity.com/shop/grasscity/scan/fi=products/st=db/co=1/sf=category/se=herbal%20smokes/sp=results_subcategory/ml=8/tf=ourprice/to=n/va=banner_text=/va=banner_image=.html

I ask because i was thinking of buying some, so if any of you can gimme advice or your opinion of whats good and whats not i'd deeply appreciate it.


Thanks.
