Summary: I got this mouse a while ago, and for a time it worked out great. However, due to the fact that the idiot designers neglected to put flex support or anything at the ends of the wires, you WILL get fraying and eventual breakage at both ends. Get a mouse made by somebody who knows basic design.
Summary: After only about 6 months of use, the mouse now randomly disconnects and reconnects every few minutes for several seconds, which is extremely frustrating and disruptive of whatever you are doing. Looking around online this seems to be a common issue with this mouse and there does not seem to be any definite fix for it. It is disappointing that the quality of logitech products has fallen so much in the past few years.
Three Strikes and Logitech Is Out Wth This Product!

Summary: I purchased three of these Logitech G400s for use by three different people on three different systems and all three were experiencing random drop-outs within three to four months of use. These G400s are not "disconnecting" like my four or five year old MX-518 with cable problems, but instead they simply seem to randomly freeze up for 20 or 30 seconds at a time. I'm very dissappointed with the G400 as compared to my old MX-518.
Summary: I owned an MX518 for years, was a great mouse. When it finally died, after years of service, I wanted another one, but they don't make them anymore. Then comes this mouse, the "replacement" for the MX518. It's a horrible mouse. I bought 5 of them for my company and all 5 have died in less than 6 months, either the left and/or right mouse buttons stopped working, the optical light stopped working, or the thing just would not stay connected to the computer (as if you were...
Summary: When i opened the package, i noticed that the mouse was making a rattling noise when shaken, like something broke off internally. It works fine and everything, and i love the feel of it, but im pretty sure that i got a defective unit
Summary: Pros: The shape off the mouse is good for small hands and the buttons are within reach at a decent price. It is smooth and decent for gaming that does not require too many skill buttons. Cons: The software does not work since window 7 does not recognize the mouse for the software to work. After plugging it in a couple of times, windows recognized the mouse but the software accompanied with the mouse does not.
Don't be fooled, this is nothing like your good old Logitech mouse from before!

Summary: I know you loved your old Logitech mouse. I know the G400 looks just like it. Please, don't get suckered like I did! I had a Logitech MX518. Great mouse! Before that, I had the wireless Logitech mouse that looked identical to the MX518. Also a great mouse. Recently the cord on my MX518 developed an intermittent fault. The mouse disconnected ever so often when the cable was flexed close to the mouse housing...
Summary: My game of choice is Fluffy Bird Flash--silly, but there you have it. The game slows down after a few rounds and it becomes difficult to drag the little birds around. I thought a new mouse might help. I was hoping this one would do the trick. But the mouse is way too large for my average-sized woman's hand. It's longer and higher than my other Dell mouse and I really can't use it. I have no idea what to do now except to switch back to my old mouse.
Summary: This mouse is definitely not worth the money. I had a Logitech MX 510 mouse which lasted me about 10 years it was awesome, I bought this mouse because i saw it had similar buttons to the MX 510 but it works completely different it is basically a well dressed basic mouse given with the purchase of a computer...I do not like how it works at all I guess my hands have been spoiled by the MX 510 feel.
