Alzo, you’ve really made my day. A little trinket like this, which you give as a free gift with an order, really is a great way to make a good impression. Not only has this piece of rubbish not worked since I unpacked it, but when I enquired about a return, you told me that I couldn’t return it because it was a gift and isn’t covered by the returns policy. Then could you tell me, in answer to my question, what should I do about it? So you’ll say that you’ll pass it on to the centre, where they’ll sort it out, and you’ll contact me by email. No reply has been received yet. Thank you. Thank you.

Returned, I'll take the JBL 5
Design
Pairing speed with mobile
Easy to use
If the LEDs worked like they're supposed to, it'd probably light up nicely: )
To make the sound audible enough in the room, at least 70% volume was needed -> then the battery lasts about 4 hours
The LED light setting worked for one side only, the other remained in a mode causing epileptic seizures even in a perfectly healthy individual
