I wouldn't call it "generic", in fact I think it smells quite nice. However, it it not my favorite summer fragrance, and I find it too short lived - even for its type. So, for the price, there are many many others I would choose over it.
So, if you love the smell and are ok with the longevity, you should get it. All the alternatives I would list would be better summer fragrances (IMO), not necessarily ones that smell very similar to Erolfa.
