Query: Review of Plantronics Voyager 510 Bluetooth Headset

I'm sorry this review is so late. I've been so busy at work and with family matters since I purchased this item, that I never contacted you to tell you this product NEVER worked in the first place. This product was ADVERTISED AS BEING COMPATIBLE with the Palm Treo 700p Smartphone. So I purchased it. It never worked and I attributed this to the Treo 700p as being the problem. Today I went on the Palm website to the Bluetooth compatibility info for the Verizon Wireless Treo 700p Smartphone. It specifically lists the Plantronics Voyager 510 as NOT being supported by the wireless Treo 700p. I couldn't believe it. I hope it's not too late to rectify this error. Thank you.
