Anyone use these training aids?

[atomheartmother]

I just finished a series of 3 lessons, with the last one focusing on keeping my right elbow close to my right hip and swinging on the correct downward plan. We were also working on swinging down on the ball. If I were to just get one of these training aids to help focus on these skills, which would you get? Has anyone used any of these?

I'm also curious about this gadget, but am a little more skeptical due to the price.

Get smart and adapt things to become taring aids. Often the purchased aid is used a couple times and then no more.  Use stuff laying around with a bit of smart adaptation, to avoid used purchased stuff laying around.

For you I would take each lesson while it is fresh in the mind and a Goodwill golf club. Cut the club off about 12'from the grip and attach a heavy weight to equal the feel of a club. It don't have to be perfect. Tape it on tight

Then I would turn all the lights off in a room so it is just you, your thoughts and the short club.  In slow to moderate motion walk through all the motions you are being taught. YOU WILL DEVELOP FEEL or said another way muscle memory.  Often when the training aid is gone so are the remembrances of what was being trained. Like a dog leash. No leash = no dog  Unless you do it a bazillion times until habit sets in.
