Query: Works OK, but there is a problem.

Bought this item to replace a walker without wheels and this item works okay but there is a problem with no apparent solution. The material that the grips on the handlebars are made of has an extremely foul odor that you cannot get rid of. The odor is so profuse that it can make you ill feeling and it rubs off on your hands. I contacted customer service at the manufacturer, Invacare, and they were aware of the problem but had no suggestions to correct the problem. Even though they had been aware of this problem for a period of time no action had been taken to correct it, such as, a change in material. They only said to live with it and eventually the odor would wear off. If you buy this item, don't say you were not warned!!!
