Bests & Worsts Reviews from Amazon

I purchased the Super Light Rollator in Sept 08 from Life Style Medical through Amazon. Product finally arrived after a longer than expected wait. Assembly was painless and I was excited to see my 90-year-old grandmother use it on shopping trips. Unfortunately, about the second time she used it, one of the rear wheels inexplicably broke apart and little ball bearings went flying all over the place. Luckily, she was on a flat surface and nothing happened to her. Well, I thought this will be easy, I'll simply call Medline and have them ship me a replacement wheel. Since they drop-shipped the walker to me, my order and information should be in their database. Not so easy. The first rep I talked to seemed very concerned and told me that someone from quality control would get back to me right away. I heard nothing for 2 days, called back and this time was told to return the item to the seller. I tried to explain to them that it makes no sense for me to ship back the item across the country to CA to some internet store front who is not responding to my emails and doesn't carry spare parts. I got no sympathy from them. I called back maybe 2 weeks later and after putting up a fuss, was told once again that quality control would be in touch. I seriously doubt that I will ever hear from them. I cannot believe that a major manufacturer of walkers and wheelchairs wouldn't take this problem seriously and stubbornly refuses to replace a broken part. Under different circumstances, my grandmother could have sustained an injury for which Medline would have been liable. One would think that they would bend over backwards to address this issue but all I get from them is attitude. I am never buying an other product from them again.
