I use this little adapter for my work as a freelance sound- & light technician, and it totally does it work! Quite sturdy body and all, though i am a little worried about the female part of the adapter, cause it can be a little wobbly. Has happened for me that the signal has suddenly disappeared and just some seconds after came back. So you have to use it with care and a bit of sweet love when you work with it, which i have adapted by not leaving the cable from the adapter too stretched out, and suddenly i have no problems with it.
Its still a bit scary under gigs, but when you look at the price its totally O.K and definitely usable!
B+!
