It’s worth it.
Had it for more than a year. It’s been through a lot. It’s amazing. Sound quality and volume are awesome. It works with all 3rd party adapters (bikes cup holders, etc)But the best part for me is the battery life. I’ve been using it for 12 days and it has 80% battery. I’m not using it too much but enough to write a review that the battery is still at 80.I would buy this again. If I could connect multiple at the same time that would be even better. Maybe one day.But still 10/10 product.

Great Little Speaker
I initially purchased 1 Reinok 30 watt speaker to see if it lived up to the Amazon reviews. I will say it did indeed. Very good sound quality for the size. If you are into a lot of bass this may not be the speaker for you. The bass up button does add some, not much, but the sound is really good. The Reinok lived up to my expectation for a $30 dollar speaker. A week later I purchase a second speaker to pair for true stereo sound. I must say it does enhance the sound having 2 speakers equalling a total of 60 total watts.The one glitch I found was pairing the 2 speakers isn’t easy, and the instructions in the booklet were somewhat lacking. I didn’t want to return the speakers as they are a very good value for the money. I called Amazon, in turn my call was forwarded to Rienok Tech Support. The technician was great, and very helpful in pairing the two speakers. Thus far it appears to be an excellent purchase.

Music from my iPhone
The technology for getting classical music for me. I prefer the old tech but those devices are obsolescent.

Don’t do it.
Sound was ok for an inexpensive speaker- not a ton of bass with the “bass boost” but not bad. The speaker got fairly loud without distortion. And I loved the colored lights. The lights were actually a principle reason I chose this speaker over other inexpensive speakers.Until…About an hour after I took the speaker out of its box and started playing music, I heard a weird, sharp short burst of static. Checked the speaker. Still playing- lights still going. I decided to turn it off and let the speaker rest for a bit.When I turned the speaker back on- no lights. I turned it off and on again. Still no lights. When the burst of static occurred, the speaker had not been at maximum volume, nor had it been knocked on the floor, or had otherwise been treated roughly. The lights just died, an hour after I got this thing.I contacted Rienok, and they were ZERO help. I would not wish having to deal with them on anyone! It seems clear to me now that if you purchase any item like this, anything electronic, buying Amazon’s protection plan is an absolute must, as these overseas companies provide no customer service support. Dealing with the DMV is more pleasant.I’ll have to wait a bit, but when my finances allow, I’m going to stick with a known name brand speaker, like JBL, or Bose. (Sony, by the way, is notorious for their appalling customer service. That might be hard to believe, but sadly, it’s true.). What I saved in money buying this speaker, I found, I paid for in wasted time and frustration. In the end, I just returned the thing.I know this speaker is inexpensive and has some good reviews. But save yourself the possibility of a LOT of hassle, and buy something else.
