After buying the Brand new Deathstalker V2 Pro for 250 Bucks, where i decided giving wireless a chance, i might regret it! Because the wireless connection always fails, sometimes it connects and disconnects in just a time of a second. Happens with both Options, the 2.4 Ghz Dongle and via Bluetooth. The Second thing, the Deathstalker V2 Pro doesn't show up in Synapse3.. it does via Cable but not via 2.4 Ghz Dongle, and only sometimes with Bluetooth, depends on the connection. Any troubleshooting i can do? Or Maybe i have a bad Product? But its only the connection. Keyboard feels great, when it works.
