Just though it might be worth mentioning how good the customer service has been from Logitech.
Just before Christmas the feet on my mouse started to lift, thinking I would need to purchase some more, I mailed Logitech to see if they could help. Within 8 hrs of mailing them I had a reply telling me that replacements were on their way. 2 days later they arrived!
Over the weekend I was playing a game when the lead got caught under the keyboard. I basically pulled too hard and the power cable where it enters the mouse must have separated inside. This Mouse is nearly 3 years old and has had daily use, so looks a little worn and tatty, but operated fine till this incident.
I again mailed Logitech to see if they could help. They explained that there was no hope of a replacement cable and that a new mouse would be required. For a warranty exchange I would need to produce the proof of purchase (receipt). Obviously I couldn't find the receipt after such a long time
I did however remember registering the mouse on-line which is what I explained in a return letter to customer services. I didn't hold out much hope!
You can therefore understand my delight when I returned from work today to not only have a letter from Logitech saying the replacement had been authorised, but a mail from UPS showing that the mouse was on it's way.
What a result!!
