Price-performance super. If you have used it once, it is no longer without

I wonder sometimes how these prices come about. Production, control, packaging, shipping, fees, commission and somewhere a little profit? I wanted only to build a flap even before I discovered this one on Amazon. Wood and paint should probably cost more than the finished part here, and the rest do the job as well no longer makes sense.
A brief flap. I take this to synchronize external audio sources with video. Applause was previously, but nothing compared to the constant sharp, loud and always the same tone of the flap. High very short rash on the soundtrack on all tracks to catch up with the gossip of the video image superimposing and you've got video and multiple audio tracks synced quickly safely and effectively.
The processing of the flap is more than adequate, can break not much, maybe tighten the screw.
When considering the price I can think of what you could not fault it. Strong buy recommendation.
