Here’s size comparison with the Lachesis next to t
he NZXT Avatar and SteelSeries Ikari Optical:



You can use the Razer Lachesis without the software, but it’s highly suggested that you don’t as with the software you can fully configure everything to your own personal likings, there are many options to choose from and you can store them in separate profiles as well.

I used the Lachesis with plastic, glass and cloth mousepads and had no problems with tracking on any of the surfaces, the plastic pad is a SteelSeries S&S and the Lachesis slid across it like it was on ice, I was amazed the first time I tried it out. The teflon pads on the Lachesis truly are silent as well, the S&S has a fine rough surface to it and I couldn’t hear the Lachesis at all sliding across it.

The Lachesis is a rather large mouse, especially compared to the small NZXT Avatar that I’ve been using, and it’s not so much the size but the height of it really that bothers me, it just feels to high in the back to me, but that’s my personal preference.

I gave the Lachesis a go for two weeks, and the verdict is that it’s a great mouse, but just not for me, I’ll be going back to the Avatar. It’s just the size of the Lachesis that doesn’t work for me, I just don’t care for a mouse that fills you hand what seems almost too much.

I did update the firmware and get the new drivers, but I found that at times the Lachesis can bit a bit jittery, and honestly it’s rather annoying when it doesn’t do what I want it to do. Those times are only when I’m using the mouse for my everyday things though, in gaming I didn’t notice it at all, so it does make a great gaming mouse, just, depending what you do, not that great of an office mouse. Sure it can be an excellent dedicated gaming mouse, but I personally use the same mouse for everything, and that’s what I like, I’m also not a hardcore gamer either.

I played Fallout 3, FarCry2, C&C Red Alert3, and Dead Space with the Lachesis and as I mentioned it is an excellent gaming mouse, it worked perfectly for any type of gaming.

I like the ability to change the DPI on the fly, it comes in quite handy, actually all of the options come in very handy, you can easily program several profile for different games.

The Razer Lachesis is an excellent gaming mouse that I believe any hardcore would just love, it’s got tons of features and the ability to save several profiles for different games is something that any gamer will appreciate.

The Lachesis though is just that, a gaming mouse, and it seems not to be the greatest everyday mouse, I personally prefer a mouse that I can use for everything I do, and to me it seems the Lachesis is a bit jittery when using it for slow motions like copy and paste etc.

Very sensitive
Lots of adjustments
Very slick feet
Works equally well on all surfaces
Easy to use

Oddly shaped
A bit jittery at times
