Anyone heard one of these? Are they the best now?

I was gonna get the JVC Kaboom for barbecues, but now I came across these. They sound better on the Youtube, but as you know, it's hard to tell there.

Anyone heard these and have opinion about them?
Are they the best boombox type of gear I can get these days?

Thanks in advance...
