Bests & Worsts Reviews from Amazon

I have heard plenty of online reviews that the JBL Flip is having issues with the Bluetooth signal (weak signal, signal cutting out, etc) I have written Harman/JBL regarding this issue and they have replied that they are aware of the problem and have recently redesigned the BT antenna. They provided me s serial number cutoff of GG0054-189100. All units above this number will have the new modified JBL Flip with the new antenna. They are pulling out all "old" units from retail stores and replacing them with the "new" JBL Flips with the modified antenna that is supposed to have taken care of the BT signal issues of the old units. JBL will be rolling out the new units in a few weeks (early March 2013) so please check the serial numbers before you purchase to ensure that you get one with the better BT antenna. Just sharing...
