1 jack works perfectly, one other does not at all (the little red LED does not light and decision is not lit), the third works as if it were almost out of range (then obviously it is barely a few cm and clear).
I found it interesting product for the price, but then suddenly, with only one functional grip on the 3, it comes much more expensive!

(Update): 1 outlet is working when it wishes (forced disconnect-reconnect + initialize each time it does not work), the second turns on but does not answer the last remote is it always HS .
