I had a defective control pod on my logitech z-680s, the headphone jack won't work. Logitech replaced it for me, but i had to pay and ship my defective one back to them first, which rendered my speakers useless for 12 days. I wasn't too impressed with their RMA service. IF they really wanted to impress me, they'd ship my replacement pod to me wth a return shipping sticker, then give me 15 days to send the defective one back or charge me for the replacement. That way i still would've had use of my speakers in the interim. Regardless, they didn't try to cover up and refuse to replace it or anything so i guess i can't really complain that much.
