i decided not to get the zaino kit for now..

I'm sure it's fine. I believe there are only like 2 manufacturers of clay bar compound, so it's all pretty much the same.

Yea clay is actually very generic, most people are just relabeling someonelse's product. The only thing that sucks with the Mother's kit is that the bar is only 80g. I had that one and then later I started using the 200g clay bars because you get 2.5x more. The bar is so big that I cut it into section of six. I also am not a huge fan of their quick detailer, I think there are other ones out there that are far less streaky. However you should be fine with your purchase to get the job done. Let us know how the results come out.
