Yeah, I got the warranty too. It's only 3 bucks. If you buy one of these, get the warranty. If ANYTHING happens to it, bring it in, and they'll give you a new one.
These things also come with 4 replacement blades, which is nice.
In the english dub version, they have changed some of the pop culture references to english ones. I LOVE Sgt. Frog! I highly recommend it for some laughs.
