Query: Meh, at best!

Just read everyone elses reviews! That sums everything up. I bought this combo set to replace my MX5000 mouse that died (due to heavy use) and to finally try a cordless keyboard.Well, Logitechs BIGGEST mistake was discontinuing the MX5000 mouse. I had mine for almost 5 years, and I spend a lot of time playing WoW.The combo isn't overly bad, but it's not up to Logitech par. At one point, Logitechs bluetooth dongle created problems with itself. Meaning, the installed driver for the Keyboard/mouse combo had a problem with Logitechs drivers for bluetooth headsets. I don't have a bluetooth headset, but I did have a Keyboard / mouse that no longer worked.To sum everything up:"Buyer beware." on this combo!
