Logitech PRO Review

Based on the relatively simple shape of the Logitech G100, the Logitech PRO in its elegance is aimed at the no frills, no compromise competitive gamer. Using their experience and know-how, Logitech have created a lightweight (83g) yet robust mouse by using hard wearing materials, mouse buttons rated for 20 million clicks, and mouse feet rated for 250KM surface travel and thus are backing the PRO with a 2 year warranty.
