wide angle converter

Hi, I have search but didn't find any posting on this subject here. Today, someone shows me Vitacom wide angle converter. The IQ isn't great but OK for the price. I came across another posting on B&S in one of my local forum and he claims this is a Nikon brand converter. 'OpticZeis Digital WIde Angle W/Macro 0.5X Germany 67mm'.

I would like to hear if anyone has used, owned or know anything on this item. Many web sites state wide angle converter is a waste of money. I have used Raynox for macro and find it perfectly acceptable.

One youtube claims wide angle converter is for close up shots such as within a room and not for landscape.

Care to share your experience and what is a better buy

You might like it at first, but after using it for a while you will wish you bought a good wide angle lens to start with. A 10-20 come to mind. These gadgets that you put in front of your lens is just money spent for nothing. This is only my personal opinion.
