I've never had any major issues with this snug, easy to use, comfortable bluetooth device. I have encountered some technical issues when activating the device with my cell phone already turned on. However, I assume that these minor issues would occur with most other devices as well. I would advise that you wait for a sale for this item as new devices are constantly entering the market. Finally, the battery life with the device is average and I find that it constantly needs to be recharged even if not used or engaged.
