I bought a YYF Popstar from Swag daddy earlier this week, my opinion-
Pros:
1.Very, very fast transaction and shipping, I payed the invoice and he shipped it within 1 hour, got to my place two days later.
2. Yoyo is just as described, ano is in good condition, etc.
3. Pricing was reasonable
4. Packing was GREAT! Shipped in two halves, one of which was wrapped in paper to make sure that they would not hit each other in transit. The whole thing was then wrapped in a layer of bubble wrap (the big bubbles, not those little chinsey ones).
5. Extras! He very generously threw in some string, trading cards, and a sticker.
No cons in the least.
Well done Swag Daddy!
