Has Anyone Tried the Sonos Boost?

Has anyone used this with their Sonos Connect system? I have a Bridge and with dodgy wifi around here I'm plagued by dropouts when I stream. Sonos says this device would be a huge improvement, but has anyone here tried it?
Here are a few comments from people who have it and/or tried it.

Seems to work well for most of them.
Thanks Mofi feedback looks good from the few who tried it thus far.
