Previously I have reviewed this product as hopeless and complain to Mahindra. Mahindra has tried their best to rectify all my complaints and they have done good job so far. They have replaced Battery free of cost after 1 year of running. But issue is with the product if they can improve it then definitely its a good buy.
Hopefully Duro DZ (New Model) is better than previous one. So give it a try and take decision accordingly.
