Received numerous spam emails after signing up, I was supposed to receive a product and it never arrived. It's not just me though, numerous friends of mine either got the wrong item, not all items ordered or it never showed up.
They also have tons of scam links on their site and their business practices are shady, including them asking people who use their site to leave dishonest 5 star reviews!
Ridiculous, dishonest and possibly not legal, avoid this data mining site at all costs.
