Invacare Pronto 51 - hardly used- Smooth and whisper quiet - Two brand new batteries - Has horn! - Controlled by toggle switch on arm of chair - Weight capacity is 300 pounds - product is located in Richland, Washington.  Chair was not used very much at all and is in good shape.  It has variable speed control from slow to fast in increments. It is pretty zippy and turns on a dime.  The batteries are brand new and toggle switch handle is also brand new.  I inherited this so have no maintenance history.  It comes with the Pronto 51 manual.  If anyone desires a "video" of it operating just email me and I can make one and send it to you.  Please feel free to email me or call/test me if you have any questions about this chair.  I cannot think of anything else to say about it except that it is very responsive and a great way for someone to get around.
