Query: Don't buy from Ocean Reef Electronics

While I would love to give a review on the iPod nano, the product sold by Ocean Reef Electronics is no longer working after 90 days. They refuse to replace the defective product and I for one will never purchase any product from them and would suggest Amazon discontinue any relationship with this seller. CAUTION to all who consider this retailer as you will get ripped off.
