According to my personal experience this courier service is very good once my father medicine was finished and that medicine was not available on local medical store I searched in many medical store so I decided to buy online so I ordered that medicine from 1mg.com and after 1 day they shipped my order by DTDC courier and the seller city was mumbai and my shipping address was Allahabad I thought it will take 4-5 days but they delivered my product within 48 hours I was happy with the service and Customer service was very good.
