How do you stop Hands dropping? Shoulder dropping? and improve confindence

My son had a problem for years with dropping his back shoulder as well. We tried several different hitting coaches ($$$$$) and none of them could fix the problem. The thing that finally fixed my sons problem was constant hitting on the "instructo-swing" tee. I'm not trying to endorse a product but just saying what finally fixed the problem. I keep thinking off all the money I would of saved if we would of used that tee sooner.

Count me as a second vote for the Instructo Swing training tee. It ought to cost less than it does, but it's pretty durable and will last pretty much forever.
