The delivery was quick and efficient.  Unless I'm not using it right, I find the heat has no settings, and I wish I could have heat without the massager on. Remote is very sensitive. 
I am managing it, but my husband can't seem to handle the remote because of its sensitivity and therefore won't use the chair.  Kinda defeats the purpose as I bought it for him.  Otherwise, the chair itself is very comfortable.  Hope this helps.
