Query: Not worth it

This was my first purchase of an airsoft gun. The gun seemed fine but i quickly learned that the hop-up feature made it very inaccurate and worse, the sight on the gun fell apart within a week. So i can't really recommend this product. But even more disappointing was the interaction with the seller. They were willing to take the gun back for a replacement but i had to pay return shipping; it took almost a month for them to ship the replacement item and then that item never arrived and they claim it was lost by UPS and they would not ship another gun until they resolved matters with UPS. They simply have no concept of customer service. Thank god for Amazon who are exactly the opposite and have helped me every step of the way. Ended up buying a new gun from a different seller.Update: the missing gun showed up so now i'm stuck with 2 guns because i already bought a replacement... still not happy with their gun quality or service so keeping my one star rating.
