Run small Good basic low-key flip flops. I tried to adjust the settings to smooth it out but nothing worked. This is the stand to get unless you desire portability. But Im not gonna review both units here, so for those of you looking for quick pros & cons, here you go. ) and seeing if that works better. They have been great for phone calls and listening to music. This thing is huge. Pour le prix, on ne peux quêtre satisfait ! I tested my wife?s iPhone 11 Pro Max and my 12 Pro Max and no issues.
