Beginner* The only adjustment in there is the core tension, adjustable with a philips screwdriver #1 it is the best way to start at a budget, and with a little extra I would throw an oil you want to test out, but for that cube specifically it would be good to keep/ opt for speed oil because it will make a difference, but playing with this everyday for me to get the basics and get better, then i'll switch to higher cubes to try to reduce my solve time. With many algorithms still to learn, I will say it again, very good beginner at a budget cube.
Would recommend spending slightly more on dayan or moretry cubes, while on sales they were 4-5$ more making you avoid the oil and whatever extras for you to keep a much better cube overall.
