Seems like most units just needed a new battery

I have to say the battery is not bad

I love its portability and the battery last for at least six hour when we took it to the beach.

Perfect - great battery life, plenty loud enough, works great

I ordered two of these UE BOOM's, they are great; mobile, long battery life, loud without distorting, good bass for the size, decent downloadable app and the ability to create stereo sound using two at a time

Great battery life

The only cons is that the battery doesn't last the 15 hours it says, by the end of the golf round, 4.5 hrs long my battery was almost drained

Great battery life , sounds great

Sounds great, great battery life!

It lasted for about 15 min then the battery died

worst battery life ever, after about a year with very minimal use it just stopped powering on and won't last longer then 2 hours at full volume, pitiful battery amazing sound.

The battery doesn't last like my other new one.

Like brand new, battery last very long

A forward thinking individual should have no problem replacing an old battery with a new (higher capacity) battery

worst battery life ever, after about a year with very minimal use it just stopped powering on and won't last longer then 2 hours at full volume, pitiful battery amazing sound.

Works well - battery lasts for HOURS (12 hours

Logitech is swapping for a new one.just giving my experience with this refurbed unit, hopefully the one they will be sending in replacement gives much better battery performance.

It has an amazing battery life and came fully charged!

well it only has about 3000mah battery.

Haven't had a chance to run the Boom end to end, but I'm seeing quite decent battery output over a distributed span of time and usage

Battery life pretty good

Excellent product , nice sound, battery last days of playing

Good battery life

Great battery life

It arrived with a dead battery

Great battery life.

Loud, long lasting battery, extremely durable, extremely pleased.

fantastic 360 sound with enough battery

I really wanted one of these but looking at the reviews, it looks like 50% of the refurbs have bad batteries.

Perfect - great battery life, plenty loud enough, works great

sound quality isn't as good as my ~2006 Logitech ipod speaker system, but this is definitely more portable and the battery lasts much longer

Works fine but the refurbished UE Boom arrived with a bad battery

Battery drains VERY quick.

It gives me maybe 2 hrs play time that sucks I think sold or gave me a bad battery boom

Both have similar quality build, have great battery life, and sound great

I bought it for a party and it works as if it was brand new and just came out of the box.

I ordered a new Boom 2 for $40 more and think I will be happy with it if it sounds as good as or better than the original Boom.
