For the asking price I'm not disappointed, upon receipt I tested it and it makes perfect so it is expected. The scope and more than sufficient (30 meters) in the studio I rarely has more than 30 meters from the model .A very well packaged and received on time, the real plus, the ability to order thereafter only additional receivers .Attention However, the user manual is in English but with a design which allows to understand the final facilement.Au a good product for a reasonable price
