a friend is using it bro. so far he had no issues. it wont affect iPhone at hardware level as its Qi standard wireless charger. price is expensive compared to imported brands like belkin or anker. thats the only concern I have.
Being an indian brand we could get quick replacement if there is any issue when it comes to stuffcool. thats an advantage I think.
Is the belkin insurance also valid in india, did they mention it in belkin india website? that has to be confirmed too. then you may go with belkin. many of my contacts using belkin products and no complains so far. I am using some belkin accessories too.
