Should be able to leave reviews about all products, not just select ones. Now that I've left a negative review, I no longer have the option to review anything, and I've bought some real junk lately. No way to warn others. Add to that how they delete negative feedback when a seller lies. Very corrupt app. Slow, glitchy. Searches are sometimes useless. Instead of searching for precisely what I want, they pull up only vaguely related items, hundreds that I have to look through to find what I want.
