Buyer beware!!! These are not the correct compression feedback devices. I ordered them twice and returned the first set thinking it was a mistake and they sent original pistons a second time. There is no light to give visual feedback of compressions as pictures.

Love that I could update my mannequins without having to buy new ones. Units work very well. Would have been five stars if they would have come in a padded bag like original non-feedback ones that came with the mannequins.

The product sent does not match the pictured product. I was needing replacement mechanism that provided feedback, however I kept receiving their original mechanism without the student feedback.
