Cheap and 1000x magnification are mutually exclusive facts.
To get to 1000x you usually need oil immersion objectives and a reliable mechanical design to hold everything steady and in alignment. The 100x objective plus the 10x eyepiece will cost $many alone. In Australia the cheapest 100x oil immersion objective I could find is AU$260 and the necessary 10x eyepiece is guess about AU$30 at the cheapest. Plus a microscope body to hold it all together. Think more like AU$1000 all up to get something reliable and good as a minimum to do reliable and convenient 1000x observations.
Naturally 1000x is limited in use and more for stained bacterial material or sliced tissue samples and the like, depth of field is measured in microns so only thin or flat things can be viewed and they need to be carefully prepared in a slide with a glass cover for the oil immersion objective to work. Looking at living pond life is more down in the 5x to 50x linear observation range, which is what I suspect that linked cheap device handles.
My guess the "1000x" in those cheapy "microscopes" refers to 1000x area magnification and not 1000x linear magnification, so the likely limit is maybe 32x linear magnification (square root of 1,000). Common marketing trick with cheap microscopes and magnifiers.
They are fun to play with but most people soon tire of their inadequacies, I even have a $10 or $15(?) clip-on for a smartphone or tablet that gives reasonable super macro results. There are better ones of course

among the regular 'scopes this was buried, which is something I've been thinking about...no idea if this is any good, I just looked at it myself...

anybody have any experience with something like that?
Nice idea but don't expect good image quality or reliability at those prices.
