Would award five stars for the mobility handle. This rail is one of the better suction rails on the market with a comfortable grip handle design and raised texture on the inside wall side aspect to assist with slip resistance grip prehension. This is one of the better suction rails I have seen on the market to assist with a safer fixing with the green and red colour code indicators to guide with the rail installation ( provided that the user is not red/green colour blind ) and the underside spring loaded pin is an additional mechanism to guide with achieving a firm fitting. The rail is a practical versatile solution to assist with ambulant mobility and transfer management in a bathroom toilet area and I would buy this product again. The fitting rail instructions are both clear and easy to read.
