1 out of 5 eggsLate to the party

Pros: Nil

Cons: This mouse worked in my PC for about 4 days. As the title suggests I am late to the party on this one. I never got around to writing a review on it because I felt so defeated at the time and didn't know what to do. I contacted newegg for an RMA which was approved. This inspired me to just immediately purchase a different mouse from a more... LOGIcal and TECHnical company. That mouse lasted me many years and in fact the only reason I ended up replacing that one was because I wanted to get one of the newer mice by the same company and I gave the old one up to a friend.

I never did get around to completing the RMA on this device because once I got my new mouse I just didn't care anymore. The experience I had with receiving a faulty device from RAZR made me decide to never purchase another one of their products again. Yeah it was one bad purchase out of 3 that I had with them but honestly that's all it takes. If I had purchased this mouse first and had it be faulty I would have stopped immediately then too. On the other hand if I had been purchasing enough of RAZR's products to keep them in business and put their children and grandchildren through college and I found that i had purchased a faulty mouse, I would never do business with them again in that scenario too.

In Alphabetical order you need the following to be successful when producing a product:


If you don't have COQS then you suck.

Customization- this could be as simple as color choice or ability to configure what the X , Y and Z buttons do etc...

Options- Maybe I don't like this mouse... too bulky etc.. what do you have that's more ergonomic or a small form factor for someone with small hands.

Quality- I shouldn't have to explain this but one faulty device is a good enough reason to not trust the entire batch it spawned from.

Support- I'm not sure if RAZR does this or not (maybe they started doing it and I just am unaware because I haven't been a cusotmer of theirs in over 3 years) but they should really throw in one of those "Don't contact the retailer" cards call our (american) support and we can troubleshoot or warranty replace the device

This should be the bare minimum anything more than this is icing on the cake. hopefully RAZR still reads these reviews.

Other Thoughts: Don't buy any RAZR product ever again if you've purchased from them before. There are other far superior competitors out there that are much more deserving of your money.

If you've never purchased from RAZR before, be glad that you saved your money.

Manufacturer Response:


Sorry to hear that you had issues with your Razer Lachesis (it's not RAZR--that's the Motorola flip phone). It sounds as if you never made an attempt to contact our Customer Support, so very sorry if you were unhappy with your mouse. We would have been happy to assist you with fixing your mouse, or in a worst-case scenario--replacing it. We appreciate your fun acronym, but in the future, please contact us if you have an issue with one of our products. That goes for Razer as a company, as well as any other company you purchase a product from.

Thank you for understanding.

5 out of 5 eggs4 years in and its great!

Pros: I purchased this mouse when I began playing PC games and wanted something a little more responsive and sensitive than a standard mouse. This one has worked great for games and has and has multiple setting profiles so I could swap between game sensitivity and web browsing with just one button. Side and top two buttons can all be re-programmed to desired buttons/macros. Responds well and only requires light pressure to click and move.

Cons: Can't seem to program the button that adjusts the sensitivity to do anything else (but was able to program all the other ones so it might just be me).
Can sometimes bump the side buttons unintentionally but hasn't been a problem since I got used to holding it.
Its shape is not for everyone! I have a smaller hand and find it quite comfortable but many friends have complained about its size and lack of an "ergonomic" bump more common in game mice today.

Other Thoughts: This shape is not for everyone! I adore it and it has lasted me 4+ years but the shape can be uncomfortable for those with bigger hands. Still works great after lots of use and abuse :)

1 out of 5 eggsAwful mouse

Pros: None

Cons: Price
I just recently started using this mouse after my Diamondback died and boy are these two mice night and day. After having the diamondback flawlessly working for years and years I plugged in the Lachesis only to have abundant amounts of problems. I am experiencing the same choppyness and mouse "lag" just in windows...don't get me started about in game.

Hopefully Razer will not hassle me trying to get this abomination replaced like the other customers have experienced. Hell I would trade down for my old Diamondback.

1 out of 5 eggsmiserable

Pros: Initially the mouse was pretty good - very ergonomic shape that didn't leave my hand looking like some kind of arthritic claw after a couple of hours use.

The seamless top of the mouse also made it easier to clean.

Cons: Terrible, terrible, terrible support. No windows 7 drivers for months. Glib, asinine responses to my queries about the dreaded skipping bug.

Mouse died yesterday after owning it for about 20 months. Was expecting so much more for an $80 premium mouse.

Went and bought a saitek Cyborg RAT7. So far it hasn't exhibited anything like the same problems.

Other Thoughts: RAZER - if you're reading this, I'm never buying one of your products again. I ran into the same problems with Logitech after using a MX500 then a G5. Both lasted a few months at best, and unsurprisingly I'm loath to use their devices either now.

5 out of 5 eggsEverything I Expected

Pros: Nice "coating," feels good in your hand.
9 Buttons - easily set up
Has proven durable over the year or so I've had it
Ridiculous DPI settings - whenever I need a sensitivity boost, it's a very easy and fluid maneuver to go up to 4000 and back down to 900 or so.
Matches my "electric blue" LED theme
It's also an ambidextrous design, which is cool

Cons: The 2 buttons on the left side aren't programmable in-game (or out of game, for the most part). I don't believe Vista recognizes them.
I've noticed that using buttons on my mouse as opposed to buttons on my keyboard for actions in-game have a slight delay. In FPSs, for instance, I often use one of the side buttons for melee attacks, etc. However, I've noticed that when I use a key on my keyboard for such actions, the response is noticeably quicker.

Other Thoughts: I love this mouse. In fact, I've loved every mouse I've ever used that was made by Razer.

When I first started taking gaming seriously, I purchased a Razer DeathAdder several years ago. Since then, the computer I bought it for has basically gone the way of the BetaMax, but the mouse still works just the way it did out of the box. When I upgraded to the Lachesis, I gave the DeathAdder to my brother (about a year ago) and it's still working great to this day.
You can't go wrong with Razer.

3 out of 5 eggsLogitech > Razer

Pros: Looks good.

Hardware is up to par.

on screen profile indicator.

Cons: Bad Software.

Feels cheap.

Cheap usb Chord.

No weights.

Profile switching is not instant, the mouse shuts off for about 2 seconds and then activates the profile.

Other Thoughts: This is my first time trying a razer product and will be my last. Logitech is by far superior in all ways. The razer software is garbage. Its unintuitive. The mouse hardware is simply limited by awful software. When setting up mouse profiles for different programs I like to have my mouse auto-switch. For example when I launch COD4 I want the mouse to auto-switch to its cod4 profile. The mouse can infact do this, but guess what? After you exit cod4 it doesnt automatically switch back to defualt profile. Since I have the hardware profile buttons disabled on my COD4 profile, I have to manually change it back to in the software. Simply idioatic. Logitechs dont have this problem because they are smart. Another garbage feature is its sensitivty and DPI profile settings. You cant tell the mouse I just want 1 DPI setting on this profile. Dumb! Profiles are locked into "Global" X Y sensitivty. So all your custom profiles have the same sensitivty just different configs for DPI. super dumb!

1 out of 5 eggs

Pros: The mouse feels very nice and is visually pleasing.

Cons: Mouse died within 5 months of ownership. It would still right click but the cursor would not move on the screen. I tried moving it to a different USB port and rebooting to no avail.

Other Thoughts: I've read responses from the manufacturer about flashing to the latest firmware. I'm sorry but I expect a mouse to just work. It isn't like this is new technology that should require being flashed. We've already been using the mouse as a pointing device for far too long for them to expect us to have a Win XP box sitting around so we could flash their device. This is the last Razr product I will own.

4 out of 5 eggsCould be a bit more sturdy

Pros: Slick looking. Fast response. Nice mouse clicks.

Cons: It just feels cheap and flimsy compared to other less expensive mice. It's also extremely light which isn't the best either.

Other Thoughts: Scroll wheel is clicky but not too bad. Add a few more ounces and it's perfect, but that's just my personal preference.
