Has anyone tried golf ball finder glasses? You put them on and you can see the ball better in the grass.?

Im intrested in buying my husband a pair of golf ball finder glasses (made by Visiball I think), I know what that can do, but they now have to models. They have the v-100 (its the sporty looking one of the two, the one I think my husband will like) and they have the v-200 (the new style, I dont think he will like the style as much). My question is - Would the v-100 or v-200 see the balls better? Or are they the same with differents styles? If you have ever tryed them your input would be appreciated to (do you like them? Do they work?).
