Product is a good choice for pots the size of those shown on the picture, but might be unstable for large pots on the top shelf.  Included 10mm wrench may not last for the assembly (mine didn't) so best to use a real wrench if you can.  Pay heed not to tighten any of the screws until all shelves are installed to prevent warping.  Overall a good value.  If additional stability is needed one might cut a larger board for the base and screw it into the unit from below using the 10mm screw holes (one at each corner where the feet attach).  In such case, remember to recess the screws to avoid scratching your floor of course.
