Product review (1 stars): Too small, late delivery and NO RETURN!
They include 5 sizes of adaptors, but unfortunately they are all ridiculously small and none of them fit. There are 4 D shapes and 1 oblong shaped adaptor. Read the description carefully or choose another product. I jumped to a $6 conclusion that with 5 sizes, surely one would fit.. $6 I cant get back as these are not eligible for return.

I suggest leaving this seller behind and just find a better source. The 2 day delivery of prime took a week, so that is impressive as well.
