I have purchased many logitech products. I think your company sucks and makes terrible products because you are too concerned with getting into my life. Your flow is a complete failure. I have had three laptops hooked up and it work intermittanly. I sent one computer back, returned all my mx products for refunds and will never buy another logitech product again. You are complete failure of a user friendly company. I have had a miserable experience with Logitech and will make sure that all within my sphere of influence understand this. I feel the same way about microsoft corp and other large tech companies.
