I don't know why the price went up maybe because I was left alone? In any case, I suspect the quality of Chinese tools and products, but I know there are more capable manufacturers in China (prices are closer to US prices), but it's always hard to tell what you'll do. receive. In this case, even for $100, this is a good manual XY step for design and production. I will test it on a microscope at high magnification, making measurements and checking, but it doesn't seem to have any noticeable play, it has an adjustable axis tension knob and micrometer graduations are handy for repositioning. Mine was on sale and definitely worth the price. It would be nice to see a Z axis and a pan axis from this manufacturer.
