Hi All, Do any of you use a scooter for getting around? Dad is thinking about buying or renting one, but we know very little about them. The only brand name I know is Rascal, having seen TV ads for them. Could those of you who use them post some info on brands, styles, advantages & disadvantages? Dad cannot use his right arm and has some difficulty getting up and down. Jane K. (daughter of Fred, 80/1-MSA?)
