I also have a mouse IDENTICAL in physical makeup somewhere which i call a zombie mouse. Cost like £5 and i've repaired the damn thing more than a dozen times and it still lives on. Cheap crap mouse of course, but it serves its purpose. Guess the chassis design is being shipped in to these various companies.
