ANLEONMTG-200 wireless tour guide language interpretation system Simultaneous translation Guided tour groups (30 Receivers)

I am a Québec City tour guide. I orderred 6 MTG-200 receivers and 1 MTG-200 transmitter. The product had not been reviewed but I took a chance on it because I assumed it was a newer, improved, version of the MTG-100, which had positive reviews (MTG-100 has an LCD (frequency/volume display that is easier to read in sunshine).The product arrived as advertised: simple plastic cases (not flimsy though), nice simple ribbon necklace, as well as a pocket clip. Everything has worked perfectly over the last year and customers rave about the sound quality. The after sale service is fantastic! I wrote to the Seller to mention that the ear buds fell appart almost instantaneous (most every kind I've ever tried do that) and about 5 minutes later I got an email saying replacement buds were on their way. Since then I have bought 6 more units and one spare transmitter, just in case. They arrived with a new type of ear buds, solid and reliable like I've never been able to find anywhere.To say the least I am impressed with the product and the service - she she!Helpful
