Hope you don't mind, I am thinking of buying a Sony lavalier tie system and saw an item on eeeeeebay item no 360306700369

Model SONY WCS-999 WIRELESS 900MHz

I dont know whether this is a good system or not and would appreciate some advice

FEATURES:
Frequency response: 100Hz15kHz
150' range, 3 switchable frequencies
3-channel selector switch
Compact and lightweight
Frequency response: 100Hz-15kHz

Will this work in UK?
