I'll make it short and sweet! The product does what it promises and is made in any case for smart phones. However, I want him to use for my DSLR ... unfortunately too heavy for the delicate part. Therefore, it is not entirely fair to reviewing properly because he was actually advertised only for the iPhone. Had it but views on a similar product where it has worked.
So, the one star deduction only due to the fact that I was slightly disappointed that it does not create even more. Otherwise, there is nothing to complain about!
