Smart phone running band

I am sure this product is good and will serve the purpose although, I did not get a chance to used the product. The strap is too small. For people with big arms/biceps I would suggest not purchasing this product as it does not fit. I now have to wear it on my forearm but even that seems uncomfortable.

Hello Hitesh, 

I hope you and your family are keeping safe and sound. I am extremely sorry for your bad experience with our Big Smartphone Running Armband.
If you can tell us about the issue in detail that is causing discomfort while using it, then it will be easy for me to guide you with the solution. However, all our product comes with 2 years of warranty. So I would also request you to please visit any of the Decathlon store near you so that the running sales advisor can check the product physically and can help you with the best possible solution.  
If you require more assistance, you may contact me directly. I would be eager to hear more feedback about our running range.
