I purchased this new in June of this year. Operation has been confirmed. I used it once at a live performance, and haven't used it since, so it's like new. I believe this is a very good deal. When I removed the Velcro that was stuck on the back, I accidentally peeled off the tape with the serial number on it... The box and all accessories are included. I am selling it to organize my equipment. Please feel free to contact me if you have any questions. I would like you to contact me with a comment before purchasing. If you have the opportunity, please consider it.
