Rated 1 out of 5 by from you have to be kidding me i bought this speaker one week ago. it sounded great in the store and there were none of the most popular partybox brand so i went with it. i played it at home. no problem. when i took it to the venue for which i bought it, i got a wireless mic, connected it, then went to connect my phone then BAM: Bluetooth Error. i was so embarrassed. i turned it on and off and unplugged it repeatedly to no avail. no more than 2 hours later, when the event was about to start, i turned it on and suddenly there was no error. it connected. i don't trust this thing. i don't have facebook nor twitter so please do not suggest to contact LG in such a juvenile manner. i am not a gen z'er. grow up, give us a toll free number or address, take this product back and refund us our money.

Rated 2 out of 5 by from BT Error I bought this speaker a little over a year ago, and I’ve struggled with it saying Bluetooth error the whole time I’ve had it. Most of the time it goes away after a little while, but now whatever I do it still just says BT error and won’t work. Also, right before this one of the speakers in it blew out, so now the sound is very low quality. Extremely disappointed in a product these expensive from a well known company. I greatly enjoyed this speaker when it actually worked it had good sound and bass.
