Drive Medical Cruiser III Rollator Walker with Anti-Tip Wheels - Lightweight Mobility Aid for Seniors & Adults - Indoor & Outdoor Use for Stability & Safety

Dunno why these are not included with EVERY wheelchair sold. They should be! The consequences of not having this type of tip-prevention on a wheelchair could be severe. Think of how helpless the feeling when your wheelchair starts falling back!Installation (& removal) is easy with a press of the button!Don't really care for the price, but most anti-tippers out there cost quite a bit more than this one.If your chair doesn't have a pair, get one!UPDATE: After six weeks of use, BOTH sets of wheels have fallen off, only one [of four] wheels was recovered. The hardware that secured the wheels is also lost, so neither of the anti-tippers are intact, except to scrape the ground in the event the chair is tipped. I am hopeful the seller/manufacturer will respond to this revised review with a solution. If they fail to do so, I will further revise my evaluation to a "Don't buy!" The hardware installed should be more securely attached.For now, this device is being scored a generous "C" rating.
