I ordered this item, manufactured by Pride Mobility but handled for Amazon by reseller called MedLife Health. The item was listed as Prime for 2-day delivery. It was immediately posted as SHIPPED, specifying that the carrier was UPS but with no tracking number. Nothing ever showed up. I queried MedLife Health and they told me that it had indeed shipped and would be there "very soon." A week later and three more queries from me and MedLife responded that they would check with Pride. I called Pride and found out that they were unwilling ever to do business with MedLife Health. I cancelled the order and MedLife responded that I could have a similar but better item in a few days for only a little bit more. I told them to take a hike.
