Really good and reliable *beginner* cube to start speecubing. 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.
Reasons for 3 stars only comes with comparing all the details of the other cubes I bought, it has a decent quality, it just cannot be tweaked as much, but it feels great foe that price range
I had bought the pioneer xman tornado v3 and a gan15-10th anniversary edition and yes that all I have to say if comparing them all.
