As a "Hot Spot Quiz" Smartphone Quizmaster I have found this perfect for what I need.
Two Radio Mics, Bluetooth Connectivity and lots of options to plug in other inputs.
It has a strong clear tonal quality to it. It's easy to over-modulate with the radio mics, so careful use is recommended.
I will probably buy 3 or 4 more in the near future for trainees at my Hot Spot Quiz Academy to get kick-started with.
Although it will never be used for the purpose of singing, I would definitely recommend one of these great and portable systems.

Great product for the price-easy to use and to carry and throws for its size and price a good bit of punch.
Big feature is battery function making it highly portable, which has yet to be tested to manufacturers time of 6 hours but if it does that on one charge -this is very good.
2 wireless mics big bonus and range of over 30 metres tried by us and still working makes it ideal for conferences/ compere and small events /spoken word etc .
Blue tooth for music is good and has add on connection for a second speaker as well as for one instrument -get the feeling could also be connected to another amp so you can add multiple instruments as well . We played around with bass and treble and that's a useful function as well

Light and good
