Review: حلو جدا
Review: These are such great value! Ultra light with everything you need and tons of mod potential if you wanna tinker for cheap. I bought this one for my son who’s looking forward to changing the screen colour, so for <$35 it’s a whole arts/craft and stem project as well as a great watch. desertcart’s stock is legit Australian Casio. For something so cheap you wouldn’t think people would bother counterfeiting them but there are lots of dupes around. F91W forever!
