I do love the personalization. But I did not recognize when creating it that there was a bottom and a top. So now my picture is upside down. My advice is if you are personalizing your speaker, look at the pictures from all angles. I do sometimes have issues with the Bluetooth, going in and out, but understand that may have to do more with the Wi-Fi network than it does with the actual speaker.
This is my second JBL Charge 4, and unlike the Charge 3 I have had no issues with this one. love the sound and the way it connects to another Charge 4 is great.
