Bitter experience

I have a bitter experience with this product, i returned 1st time as it came without a travelling pouch and even the packing was not intact , when it came for the second time, again it came without a travelling pouch and it seems the same is repacked and sent. Very bad experience, I do not trust this manufacturer.
