Query: Roseart Pottery Wheel

I bought this pottery wheel for myself, just to work pottery in an inexpensive way; however the pottery wheel just doesn't work very well. I tried it once it was forming a vase but when I tried to take it off as instructed the vase collapsed. Also the wheel just doesn't move around fast nor sturdy enough. I wouldn't recommend this product not even for children. It just doesn't work well.
