Good product, but shares a common problem...

The switch in this device is poorly manufactured. It is not a problem with logitech for the most part though. In fact the overall design of this product exceeded my expectations. The problem is with the metal contact inside the actual switch that is soldered onto the pcb that closes a circuit sending the signal that registers as a left click or right click etc. I found in the one I purchased, the metal contact was oxidized with a bluish grey (silver I assume) oxide which interferes with the switches ability to open and close as it is intended. Instead what happens is even though you currently have the button pressed down it will randomly release the click and sometimes re click causing ghost clicks or unintended double clicks as well as interfere with , selecting text, etc. If you are within the return policy of the store you bought it at, simply return it for a new one though you may experience the same problem after a while, given time for the contact to oxadize again if it hasn't already from sitting on the shelf. Option 2 would be to use the warranty if it still applies. Once again you may have the same problem again, especially if your replacement contains the same make and model of switch as the one that failed. The third option is to fix it yourself. Keep in mind this will void any remaining warranty you have on the device. Do a search for ghost click oxidize contact or something similar and there are a few different ways you will come up with to fix this yourself. I wouldn't say don't buy this product because of this problem because I don't know if logitech has addressed the issue and rereleased the product with a better switch or not or even if they are addressing it at all. Unfortunately the choice in components is often made by a manufacturer based on upfront cost rather than reliability and performance.
What's great about it: Setup, ergonomics, performance, compatability
