Careful with the magnetic ND Filters
I am using the shoulder strap, hand strap, magnetic uv filters, magnetic caps and magnetic variable nd filters. In general, I am quite happy with all the products. Just 2 things: 1. The variable ND filter is magnetic but for best use, you should screw it in. Else the spin for adjusting the darkness will not work well. 2. If you have a 77mm ND filter, The 77mm magnetic cap will be too small. So you have to remove filter after using it.
