Affiliate site linking to products.

I am creating an affiliate website where I have a list of products and when a user clicks on any of them, a new tab opens and the user is being redirected to the original product through my affiliate.

The question is, what is the best workflow?

1. the user goes to mywebsite.com/list -> the user clicks on product -> opens a new tab with the URL affiliates-system.com/link-to-product.
2. the user goes to mywebsite.com/list -> the user clicks on the product -> the new tab opens with the URL mywebsite.com/redirect-to-product -> the user sees the text & # 39; Will be redirected to blablabla & # 39; -> the user is redirected after 3 seconds.

I have seen other websites doing no.2. Are you doing this on purpose? Which is better for SEO and UX too?

Should I use nofollow for this redirection and at what stage?
