Is there a difference between this product and this one: https://www.digitec.ch/de/s1/product/logitech-g-g502-lightspeed-kabellos-maus-11033443?supplier=406802? On the other product we have more than 400 reviews. Here there are 16 reviews. But both say wireless, both have the Lightspeed version, ... Only the prices and availability are different.
