A drop of water on a flower

I've been practicing photographing. Recently I took up macro. because it's going to cost a lot to buy a macro lens, I chose a close-up filter. XPRO close-up. Give me advice whether I should return it? Here's a picture.
I bought it on ebay, just because it's cheap, and it has green antireflection membrane.

beautiful, great detail and color

Looks good. If the xpro lens is an achromatic type then I'd keep it .
