This is a good invention for persons with visual impairment. However, the following are my comments: 1. There is need to subsidize the price for low income earners from African countries (such as Nigeria, Cameroun, etc) where poverty is at high rate to afford the price. 2. There is need to update the description on internet on the lasting hour of the battery if fully charged and care and maintenance of the Display. 3. Finally, to promote sales, there is need for more advertisement on various search engines like google and removal of shipping cost (i.e free shipping) for international buyers. 4. Distribution of this machine to various outlets, firms, market, online marketing, etc where technological products are for sale. 5. There is need for the manufacturer of this Display to establish more showrooms/outlets in various African countries such as Nigeria where there is high prevalence of blindness. If the about suggestions are taken into consideration, it is hope that: 1. There will be increase in sales 2. Promotes the goodwill of the manufacturer. 3. Ease sedentary life style of life for persons with visual impairment especially among African countries. Thanks.
