Summary: Owned mine now for 18 months, for the last 6 months, freezing has been becoming more and more frequent. Now the remote has is lucky to get through 3 commands before needing the battery removed, let rest for a day and restarting. I have been keeping the firmware up to date, but it has basically given up the fight after 18 months. I will never buy another Logitech product, given the "I don't care, it's out of warrenty" approach by the Logitech "support" section.
Pros: Great when it works, which is not often enough
Summary: Returned it after 3 days of hair pulling. Battery life barely a day & a half. Clunky to hold, activity names get truncated after download so watch out if your first few characters are identical across activities. Got it from Clive Peters for $190 & foolishly thought I was getting a post X'mas bargain.
