Before finally getting in touch with EZ WALKER ROLATORS I ran in circles trying to identify an obscure part to repair my wife's walker. Late afternoon, right before closing time, Larry ( who turned out to be a honcho) spent quite a while trying to identify exactly which of several similar parts I needed for my particular model. Unsolved, Larry promised to continue research and call back first thing the next day. Sure enough, first thing the next morning Larry called back, forwarding diagrams and photos. Then he quickly sent the exact part I needed and within a couple of days my wife was back on the street using her favorite walker just in time for our upcoming vacation.
