I purchased a Harmony One remote in Oct. of 2008. It work flawlessly for 3 years. I recently got a new surround sound system. While I was setting up the new system I noticed the battery would drain quickly. I popped off the battery cover to pull the battery and replace it. I couldn't get the battery out, it appeared to be swollen. I contacted support. After a couple emails and sending them photos of the battery stuck inside, Logitech sent me a free replacement. I received the replacement less than 10 days after my initial email to support. Great support for a remote 2 full years out of warranty. Thank You very much.
