That is a mciro version of regular sized mouse. It is very light. Unlike most wireless mouse, this one needs only 1 AAA battery. Some wireless mouse needs 2 AA batteries! Pictures speak louder than words. So, look at the pictures i am attaching. I am yet to see how long the battery lasts. Is AAA battery a plus or minus point, i don't know that. I think it contributed to less weight mouse, but battery may last less longer than AAA battery. I am attaching comparison pic of logitech M185(grey) vs this mouse M!87(white) in size. Performance is equally good. If you have big hand, it may feel small in your hand. Sometimes, after shutting down computer and restarting it, mouse doesn't work. You have to remove and reinsert battery to make it work.
