If we buy your diabites check machine, afterwards we are not getting the strips, so what is the use to buy your company products, when supply is not regular and product is not available in the market.
Once, same was happended with jhonson & jhonson earlier and they were out of the market.
So if you want to sell your products, regular supply must be there otherwise the day will come and company products will be out of the market.
People will loose their confidence and trust.
