It is best to rely on quality products when it comes to personal mobility devices as the most important and primary factor to consider is the personal safety of the rider, as the rider is completely dependent upon the responsiveness, robust and reliable functioning of the equipment. Personal safety is fully jeopardized when a low quality and cheaper option is used. Using other alternates / copies of different products, one can still be satisfied by following a use and throw model, however when it comes to personal safety saving a few hundred dollars may not be the right option.
