I picked one of these up from Maplins when they were closing down, for £120, and so will add some thoughts.
For use in the house, it has some very appealing sounds, the guitar tones with effects can sound amazingly spacious, they use some clever processing to get a very wide stereo effect.
Likewise, the bass sounds are surprisingly solid for such a small unit. You can tell there is a lot of compression and d.s.p. going on to keep the tiny speakers under control, but it's really well done, and you can't get them to fart out. It also means that you can't get the bass sounds to go as loud as the guitar ones, but it never sounds nasty.
Playing music through it via Bluetooth or mini jack works fine, but has a decidedly bass-heavy bias, which I fix by having a custom eq profile on my phone.
Things I would like that it doesn't have:
1: a small strap handle for carting it about
2: built in rechargeable battery, this would really extend its use as a Bluetooth portable speaker of reasonable volume and quality
3: most of the bass effects are ok, but the envelope filter is pretty rubbish
