I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...

Ex Input:
These chips taste awesome. And unlike most other flavored chips, they actually make sure that plenty of the flavory salty goodness gets on each individual chip. Just don't pass gas near any pretty ladies after consumption. They'll totally know it was you.

I would've thrown the whole bag out if not for my convection oven. My first microwave batch turned out HORRIBLE. 1/2 cooked and no puffy/fluffy pieces at all! I popped some onto my infrared NuWave oven and they puffed up after 8 mins. FINALLY- something edible and YUMMY! Glad they are healthier than the MSG/other additive types of rinds, but kinda high maintenance as far as how to properly prepare them. I think I will try to find easier-to-prep ones...bummer.
