I've only had it for a few days (Nov. '19) but it is great. Small, light weight but gives great sound. I got a Wonderboom 2 for $129 at Myers - I was told that the original Wonderboom is no longer available.
I am going overseas soon and this thing is perfect. The only downside is not the speaker itself, but the so-called manual - next to useless. Go online and view the very good youtube videos by Max Dalton - brief but very informative.

Great sound quality.
Simple operation, can skip songs using a speaker button.
Easy to sync and connect to.
Was a competitive price when I got one a coupla years ago, I'm very happy with mine.

I love my wonderboom, the clarity is amazing for such a small device. Easily portable and simple to use. They come in several cool colours. Even turned up loud it is so clear.

I love being able to take this camping, rechargeable and great battery life. I'm considering buying another!
