I feel that their customer service has hit bottom. Two years ago, I purchased a pair of SF5 Pros, and the service was excellent. I RMA'd (twice) and the response was very quick. I even received the replacements at the end of the same week.
Now, I purchased the triple.fis and the right channel stopped working on me, and when requested an RMA, it never came for three weeks. So I called them instead and they tell me it will take at least 2 weeks to send me a new pair.
After Logitech bought them, their service has been going downhill.
