Razer Krait Optical Gaming Mouse Review

Razer Krait Optical Gaming Mouse

The packaging is as professional and solid as those from top manufacturers like Logitech or Microsoft. No cheap packaging for a mouse of this pedigree! The design of the mouse itself speaks volumes about the amount of engineering that goes into it.

The Razer Krait appears to be a lower-cost development of the Razer Diamondback. The two mice share a lot of common points, like the same basic design, the same 7-feet long mouse cord with a gold-plated USB connector. They even use what appears to be the same 1600 dpi optical sensor.

However, the Krait only has 3 programmable buttons, as opposed to the Diamondback's 7 programmable buttons. What it essentially means is that the Diamondback has two extra buttons on each side while the Krait comes with nothing but two large buttons and a single clickable scroll wheel.

Whether the "loss" of four side buttons is really an issue for the gamer, well, that depends on the type of games played, as well as the gamer's own inclination. But for those who do not like to use side buttons, the Razer Krait offers you the same performance as the Diamondback, without the price tag.

However, our long tests of this mouse exposed a sensitivity to mobile phone signals. That could be a real problem especially if you are not aware of the issue. You may think that the Krait is malfunctioning when it's merely sensitive to incoming mobile phone signals.

We also noted a degradation in the performance of the scroll wheel. But this could be an exception affecting our mouse, rather than the norm for all Kraits. In any case, the Krait comes with a one-year warranty. So, if your Krait is affected by this problem, just let Razer know about it.

However, do not let these issues cloud what is genuinely a great budget gaming mouse. If you are not a fan of side buttons, this is a great mouse to consider. It offers you the performance of more expensive mice like the Razer Diamondback without paying for it. Just keep mobile phones away from it and you have a real bargain in your hands!

Our Review System

Tech ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a multi-tier review system.

This review system is designed to allow you to quickly receive information on the latest hardware or software. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
