"I recently purchased a Tocaviva Cornet with black nickle finish. The horn finish is absolutely beautiful, but upon initial cleaning, I discovered one cracked top valve cap on the number 3 valve, and several leaks in seams along the feed pipe. I contacted Tocaviva, and they delivered one replacement valve cap and new piping, which didn't fit properly, and would pop out while playing with a mute. I later discovered more leaking seams and asked for a replacement horn that wasn't plagued with defects, but the Manager Ben, said they would only refund my purchase. I decided to keep the horn, but now I wish I did return it because my cornet developed two more cracked valve caps. These Plastic horns have a beautiful finish, but the valve caps on these horns are held in place with chintzy locking pins that break under normal use. I strongly recommend avoiding these plastic horns, as they're plagued with defects and fall apart under normal use. For what these things cost, you could purchase a used horn that will last and sound better then plastic."
