My Experience:
+ Pairing worked immediately
+ Good sound (assessed subjectively)
+ Discreet dark green light (about 2 cm) during operation
- Regular disconnections (approximately every four minutes)
- Extremely poor open package ("frustration full") - despite scissors
Product returns.
Located joins the ranks of my other errors Logitech Products (mice with low half-life, bad software of the internet radio). Nevertheless, I'll try it with other products further, because Logitech's innovative.
If you would just get the quality under control!
