Macro diopter Lens Brands

Anyone any experience of the below lenses for Macro work?

DCR-5320PRO High Definition Macro lens conversion 3 in 1: 2-diopter, 3-diopter and 5-diopter
Opteka 10x HD² Professional Macro Lens

I have also been looking at B+W +10 diopter. I have two B+W Filters which are very good, so logic states this lens filter should also be of very high quality.

Let me know your thoughts on the pros and cons.

Many Thanks

No - although I have used Marumi, and been very happy with them. Bought from Cameraworld.
