Right now, Im playing my games with a Seitek Eclipse Keyboard and a Logitech MX518. which have both done me really good till this day. However I want a little more, and i have been considering upgrading my perpherals. 

Well I own the Razer Deathadder and I must say I`m a little dissapointed, the mouse feels good but it just doesn`t feel like it was built to last, after owning it for almost a year it tends to make creaking noise's every click I make and for some reason the button's are starting to stick, and I have never spilt anything on it.

I prefer logitech, but that's not saying I think all of Logitech's gaming grade gear is good. I actually dislike the G9 quite a lot and use a G5 (link) myself. Unless you really want a wireless mouse I'd go G5. Plus the grippy texture that it's coated in is quite useful. A couple buddies also use the 1st edition G15 keyboard, which more or less now exists as the G11 without a LCD panel. Either or should rock. I've been using a Logitech Media Elite for 7 years and despite some nagging wear and tear, I cannot find another keyboard that has slanted keys the way this one does.

My opinion on Razor is they have nice looking products but I think they're overpriced.

If you end up going with Razer, get a Copperhead. I'm on my second one, and I never want to change mouses again. I tried the Lachesis, but it didn't feel nearly as comfortable as the Copperhead (Copperhead is longer and not as high.)

This will purely depend on your personal taste and feel.  Try out products from both companies and go for something that is more comfortable to you.

I always prefer hardware that is tough and can get banged around alot. For this, among other reasons, I prefer Logitech producs.

I reviewed the Razer model a while ago.

Razer DeathAdder Gaming Mouse Review

The Razer DeathAdder is modeled on the Microsoft Habu internally but with some slight performance increases in some areas. It has larger 4 and 5 side buttons that are more tuned to gaming needs and feel so much better than those of the Habu. You can click four to five with one slick ball to tip movement of your thumb, which comes in very handy at times. The 1 and 2 buttons are made from a non slip rubber surface which is slightly concave and cup your fingers perfectly. The mouse wheel is very large and on the front decline of the perfectly ergonomic mouse, as a consequence it is even more comfortable to use. The mouse very good to use and it's precision and speed are unbeatable. It is perfection in your palm, and it feels like it. The mouse currently has the highest MouseScore Rating so far, it's easy to see why.



I would go for a Mamba if you can afford one.

I prefer Logitech to Razor. In this case, I do actually have a G9, and it kicks fucking ass.

Loving this Lachesis, got it a few weeks ago after using a Diamondback for 3-4 years.

I'm a Logitech man myself, using a G5 right now.

thnx for the imput! right now it looks like more people are leaning toward the Logitech side,

Razer DeathAdder or Lachesis for the mouse, Saitek Eclipse II or Logitech G15 for the keyboard.

I have a Razer Copperhead at home for gaming for the last 2 years.  It's solid.  Make sure you get updated drivers/firmware for the mouse.

Prior to that, I used a Microsoft 5 button mouse that felt good, but eventually threw it across the room when the batteries ran out of juice in the middle of a Counter Strike match.  I'll never use wireless again for gaming.

They are both good. They both have top of the line hardware, high dpi, etc.

It pretty much comes down to what feels better for you. We can't really help you there.

Yeah the Lachesis seems a little too much for me, i mean 4000 dpi? come on, I have an MX518 right now and that goes up 1800 and i dont think i even go that high...

"Razer DeathAdder or Lachesis for the mouse, Saitek Eclipse II or Logitech G15 for the keyboard.

Avoid the Razer keyboards.  They are okay, but not that great.

"

I have to say logitech they make products that last.

I've had both throughout the years and I'm officially a Razer guy now.  They may not last as long, but when they do work, they are the most precise and comfortable gaming mice on the market.

Ive only really had logitech and Microsoft, so I cant compare it to the Razors, but I can say I love my Logitech MX Revolution, my VX Revolution and my Bluetooth V470 although the V470 is abit small for gaming, the other 2 are awesome.

I currently use a das keyboard and a Logitech MX518 that has worked for too many years to count.

I like my mice a bit on the heavy side, and I've typically had good experiences with Logitech products (I also have a Razer DeathAdder, which is not terrible but some of the construction just feels a bit cheap). Currently on my desktop I'm running a Logitech G7 mouse (you can't even tell it's wireless until you have to change the battery), Logitech UltraX keyboard (cheap but I like it), Logitech Z-640 speakers (inexpensive but good for the money 5.1 setup that's been discontinued), Logitech Extreme3D Pro joystick, and Logitech MOMO Force wheel (can you tell I like Logitech?)

Logitech's also released a number of new gaming peripherals recently - the G19, which is a successor to the G15 (G15 has a minimal resolution monochrome LCD while the G19 has a 320x240 color LCD), the G13 (similar to the Nostromo Speedpad), the G9x (higher DPI than the original), and the G35 (USB virtual surround sound headset)

Ive been looking at the G13, looks sweet, but just abit too expensive for what it is.

I favor logitech products myself. The try before you buy idea is good though if you can.

hmm... Im kind of leaning towards the Deathadder mouse right now, at least right now a great price ($50).

I don't think it really matters about the mouse. It's the mouse surface that counts...and this is what I'd recommend you get:

Yes...those are wrist rests.

What......the.................o.0

I use a MS Sidewinder x5 mainly because i love the side button layout and it has a good feel and on the fly dpi switching for a keyboard i use a logitech g15.  I have used razer mice, headphones, and keyboards in the past.  I had a terrible experience with every single piece of razer stuff ive ever used.  Probalby just my bad luck because some people swear by their stuff. 
Basically stick witih what you have had good experiences with in the past.

I've used both and I stick with Logitech.

mx518 is the best mouse ever with the shittiest paint job.

i use saitek keyboards (eclipse 2) and a saitek x52 pro flight stick and throttle.

for headphones, neither logitech nor razer are worth two shits. you want good headphones for a good price? get a turtle beach HPA2 5.1
