Pros
Maybe it depends what branch you're in but my boss is super chill, good balance of funny/laid back and efficient/productive, and to me it's really important to have an approachable boss I can talk to if I need something or have questions etc. After training you can pretty much pick your own schedule, the work is generally pretty easy after a little bit of practice, the pay is great, and you can work as little or as much as you want. You are incentivized to sell as much as possible but you're paid whether you sell anything or not, so that's really nice.
Cons
If you're a really agreeable person who really hates to be pushy you may be a little uncomfortable with the sales tactics because like almost any other sales job this one requires you to call people you know and try to get them to buy something. You get used to it with time but it can be hard at first.
