Hi Norman, we appreciate you for posting your concern here in our forums. A higher star component will always have better stats than 1 star only. We suggest you compare the stats as well and equip it to an appropriate Club. For more info about components, you can watch a tutorial video on our Youtube channel: https://www.youtube.com/watch?v=Zb81jMdNOu0

What are the benefits of buying components with a higher number of stars in the Shop? For example, if I have a Grip with 1 star and the Shop has one available with 3 stars, what benefits will I get if I replace my 1 star with the 3 star?
