Wow. I'm that person too, that will immediately doubt these 5 stars.. but this is why you did not get a solution from customer support/or get the software to work.I've seen negative everywhere for the part of customer service/support/warranty. I had the opposite - Probably the most professional help in my case.So for new products, you are covered under the limited warranty if your description fits a common problem in the new design of the product. Accidental damage or treating your device with no care automatically raises flags. You will get denied.To that guy that got the 'return to shipper' notice, it is because you have not registered with FedEX for home delivery/notifications. They only give you that 'status' after 3 failed delivery attempts. If they attempted at the wrong address, it is on you. You did not follow instructions --- it was the first instruction that logi support told you before shipping. Instead of venting, people should be more proactive.To the software complainers, I'm assuming also a Windows user, check your firewall security (Windows Security) in-out-settings for the app. If on a private network, make sure those settings are applied there. That means, you have to also check your wifi/network config. and whether it is still under the default public status ( should not be )..... Logitech provides good troubleshooting on their site, this is one thing they have not mentioned, but it is the ultimate solution. hope it helps someone.
