Successor to the MX5xx series

Pros: Bought this to replace a MX500 I had for 7 years and finally gave out, since it was the closest thing out there. So, pros: - It's pretty close. That's all. They haven't messed anything up too much.
Cons: Time to nitpick. The bottom plate is not transparent like the MX500's. I thought it was neat before, now it's just black plastic. The cord is "25% lighter" or something. It never really bothered me before, now it just looks like flimsy and cheap. I can't dock an egg because I don't know if it's actually more fragile or not. If it's just as strong then I don't care. It has a property that laser mice have that I dislike, which is why I went with optical. It keeps tracking even when you life the mouse off the pad slightly. It's unbearable with laser mice, imperceptible with the mx500, but noticeable with the g400. Oh well.
Overall Review: The feet are different. I was hesitant at first, and figured it would take a while to get used to. I was right. It makes it using other mice feel like you're scrapping them over sandpaper. But at first it's too "glide-y", and I kept overshooting my targets (buttons in dialog windows, let alone games). Getting used to it slowly, not too bad now.
DOA

Pros: I imagine it has many...
Cons: Arrived dead, no big deal right? these things happen, but...
Overall Review: ... I put in an RMA request over the weekend, and 4 business days later still no reply. Also, shipping took longer than it would have if purchased directly from newegg. Won't be buying from external sellers through newegg again....
Buzzing problems

Pros: +Comfortable +Good wireless performance +Decent battery life
Cons: -Randomly will start buzzing, then shuts off. It takes several tries to get it to start up again. Common problem multiple people have been experiencing, and logitech will refuse to acknowledge the problem. Do some research on "G930 buzzing". -Also: I use it at maximum volume, it doesn't go very loud.
Overall Review: Good headset if you don't have problems. Do you feel lucky?
OK on sale, too expensive otherwise

Pros: Looks nice and has several neat features. +You can set profiles for different applications that turn on automatically when you launch them (a profile consists of key bindings to all keys, not just the macro keys, as well as the colour of the backlight). +Media control +USB ports
Cons: -They keys are extremely narrow. They are just narrower than the tip of my fingers, which you can imagine makes typing awkward. I imagine this is to keep the overall width of the keyboard down, which kind of worked -- the keyboard isn't too large (still, be ware if you have little desk space). -This keyboard needs to plug INTO THE WALL. I didn't realize this when I bought it, and luckily I had an extra wall socket, but I was still shocked.
Overall Review: The lcd screen is very bright and I haven't found worthwhile uses for it yet. I wouldn't have bought this for full price.

Pros: Looks great. No really, it does. Speakers are a plus, they work fine.
Cons: The buttons are confusing when it comes to navigating the menu, which isn't fantastic to begin with. Much prefer to menu on my Samsung.
Overall Review: Can't get it to look quite like my other monitor, no matter how much I fiddle with settings, but that's to be expected since different brand and specs.

Pros: Decently comfortable. Sound is fine. Mic is fine (skype a lot, everyone thinks I sound loud and clear with little bg noise). Price is awesome. Very sturdy and well built, don't expect any problems.
Cons: Outside of my ears get a bit sore if worn for LONG periods of time (many hours). It actually blocks outside noise pretty well, which I dislike (feels weird). For this reason, I wear it with only one side covering my ear, and the other is to the side of my head. I do this when I don't need stereo. USB is slightly annoying, because you can't just plug/unplug it. Plugging it in adds a sound device to your system, and then you need to go under sound settings and set that as primary each time. Didn't think of it when I bought it.
Overall Review: Most of these cons are my fault, so I only docked 1 egg. It is as advertised. Good product for the price.
