Query: Skywalker's BT500 Review

I use it with Treo 700wx...BT500 has worked from the getgo. Very simple to use, but read directions first & you be up & running in 60-90 seconds. I have only had to delete and re-pair it once since receiving it. Have had issues with lots of static on the very first call of the day, after that clarity is very good.
