The package arrived well protected, the box a little mistreated but did not damage its contents. The mouse has good assembly and weight, its cable has good thickness and excellent quality, I liked your design; the configuration generally works correctly but the custom configuration in the software does not connect to the mouse. The package took more than 1 month to arrive and I went to look for it directly at the mail office (the problem was theirs). All right with the seller. Speed. I love the design. I don't regret the purchase made.
