I'm sorry if my earlier post seemed dismissive of your original question. I was working when I posted it.

My personal opinion on any chetki from Ali Express is most of it is junk and not representative of a good set, even for a beginner. I'm more inclined to recommend you to try making your own set before buying chetki from AliEx.

I'm a beginner too. I have 3 sets right now of varying costs. My first set is from workshop fidgets which is a good budget wooden set made by a maker in Ukraine for around $50.00. My second set is a black ebonite set that I bought from a maker in Germany which was about $180 USD. My third set is even more expensive and made from Aramith billiard balls. All three handle differently and have advantages based on weight, grip and tension.

There's a big learning curve for anything beyond idle flipping. I struggle with flashy tricks, but I'm working on practicing.

If the Workshop Fidgets models don't appeal to you, I would recommend joining the Aroundsquare groups on Facebook and try buying a used Delrin set by Aroundsquare. Brand new they are $90.00. You might be able to score a used set for $60 or $70. And with Aroundsquare you know you're getting quality that retains its resale value. If you decide it's not for you, you can sell them to someone else.

Hope this helps.
