I really liked the way I got it so fast, and it works great. However, I emailed twice with no response and called twice before someone got back to me. You advertise that the remote comes with battery included and that is false. Not only did it not have a battery, but there was no place to find out what size button battery it took. I would suggest that you include the battery size somewhere. I had to go online and finally found it. But overall. FANTASTIC MACHINE. work on customer service and information buyers need.
