I purchased this item to relearn piano keys and at the same time to make music for an up coming project. So far I'm getting the hang of how easy the response and sound quality is. For a used product the shs-500 felt new, clean, and reasonably priced. 10/10 will come back and look into more of Sam Ash's inventory for more instruments even if it's used. Also very impressed with the shipping. Got it in two days instead of the whole week!
