Well, from your description alone any damage you experience within one year would fall under legal warranty in most countries, so Logitech would hurt themselves as they would have to replace/repair it. What's more interesting is how well the product works after 3~5 years. I had a few Logitech mice which worked fine, but i.e. had a matte rubber coating which inevitably dissolves and gets sticky after a few years...
