Millenium MDT4 Drum Throne Round

I bought this chair as a kit from thomann, which included alesis nitro max (amazing beginner e drums) and sticks, and what a terrible idea that was, sure its cheap and for a beginner testing the waters thats appealing, after 6 months of playing drums, alot of days i have skipped practice, stopped earlier just cause of how terrible this stool is.
It doesnt remain steady no matter how hard you try to tighten the screws to your ideal height, you will adjust it, tighten it as tight as you can, sit down and every screw will be loose, meaning it wobbles again.
The second reason why its so terrible, its so damn hard you might as well be sitting on bricks, truly ruins the fun on drums, and thus killing motivation for practice, 2 stars would be too generous for how much i hate this stool, if you want to start out on drums, get a comfier chair, anything is better than this, cause i truly have given up on alot of practice cause my butt hurt too bad, or cause i got too annoyed from the wobbling, which makes using the kick drum annoying
