High quality part, and very well made. Aircraft Spruce shipped these to me very quickly. Price is better than some other electronics parts houses.

Just the part I was looking for. There was great communication by Aircraft Spruce and item was sent out quickly. I would be happy to do business again with them.

Ordered 2 and it appeared to be real Nexus parts. The price is right but one of the jacks were broken. When ever I plugged my headsets, one of the leafs would pop out of position causing problems. If you order, order more than you need just in case this happens to you.
