Regular warning not to purchase thunderstones off a sketchy website promising "100% evolution rate". Some notable reviews include:

- "Didn't know Pikachu evolved into an eel, nice"
- "turned my tadbulb into an ugly monster beyond recognition. dumped that .... thing, right into the sea"
- "raichus apparently require 4x more food, would not recommend"
- "this product is so good my tynamo skipped an evolution stage; premium product"
- "Send this to your worst enemy and you'll never see them again. very useful."
- "My pokemon fell in love with me after using this, 10/10"
- "ruined my relationship, my boyfriend will never be the same"
- "I forgot how to speak"
- "EEEEEEEEEEEEEEEEEEEE"

The shop listing has since been taken down, and is currently under review.
