Razer Boomslang 2000 in the test: ball mouse with 2000 dpi for gamers
How already mentioned, you can operate the Boomslang on both the USB port and the PS2 port. Although you can increase the PS2 port from 40 polls/sec (Win 95) or 60 polls/sec (WinNT) to 200 polls/sec and the USB port runs at 125 polls/sec, most players who have a USB port, prefer it to the PS2 port, as overclocking the PS2 port requires a lot of computing power from the CPU.
As mentioned, the mouse has via 5 buttons. The special thing here is the size of the buttons and where they are. The two main buttons take up a good half of the top of the mouse. As is usual with any mouse, the mouse wheel lies in between. The 4th and 5th buttons are on the right and left almost halfway to the bottom of the mouse. The button on the right outside in particular (button 5) takes a bit of getting used to for right-handers, as you have to press it either with your ring finger or your little finger. The position of this key was only something unusual in the first 2 days, after that I was completely used to it and it was no longer a problem to press the key as quickly as any other.´
What is positive in any case is the processing of buttons. You can press them very easily and they are not as loosely attached as on the Intelli Mouse Explorer, for example, where the buttons wobble a bit in my opinion. In addition, the two main buttons are equally difficult to press at any point, so it does not matter where you press the buttons. In addition, the buttons are specially coated so that they offer an extremely good grip.
The mouse wheel is also very positive, as it offers a lot more gradations when turning the mouse wheel than a normal mouse wheel. According to Razer, the mouse wheel offers 45 steps per revolution, all of which are clearly delimited from one another so that you can select precisely step by step. A normal mouse only has 18 steps per revolution. In addition, the mouse wheel is not as smooth as it is on many other mice. What is positive is that you don't scroll too far as easily as you often do with normal mouse wheels. This is particularly important in games in which you change weapons with the mouse wheel so that you don't scroll beyond a weapon. Overall, the processing of the entire mouse is extremely positive and shows no defects.
In many reviews that I have I read through in the run-up to this review, the housing of the mouse was heavily criticized because it has a very unusual shape. At first I was also very surprisedthe peculiar shape of the mouse, as it is very unusual. It is very flat and at first glance hardly adapted to the hand. But here too I have to say that this is no longer a problem after 2 days. Now I think the shape of the mouse is even better than that of others. Above all, I like that the mouse is not as small as many other mice, but is actually a bit larger than the Intelli Mouse Explorer and has a greater weight. This does not make the mouse clumsy, but thanks to the 3 Teflon fields on which the mouse rests, you can move it back and forth very easily. The size and shape of the mouse is certainly not for everyone.
But how does the Boomslang achieve greater accuracy with less hand movement? What is immediately noticeable is that the ball on the underside of the mouse is not in the middle, but in the lower third, closer to the heel of the hand. Due to this small difference, the Boomslang already reaches its goal - less hand movement. The movement is transmitted directly from the ball of the hand to the mouse and not only through the fingers. The Boomslang achieves greater accuracy thanks to its higher 'dots per inch' (DPI) values. DPI indicates how many signals are forwarded to the chip when you move the mouse one inch. The Boomslang runs at 2000 DPI. In comparison, the Intelli Mouse Explorer only runs with 1000 DPI and normal mice often only with 500 DPI or less. The technology of the ball device looks the same from the outside as any other ball mouse.
So the secret lies within. If you remove the protective flap over the ball and take out the ball, you can immediately see that the ball is not just scanned by 2 small plastic discs, as is the case with many other micebecomes. The ball of the Boomslang is scanned by two permanently incorporated metal rods that run extremely smoothly.
The new Kärna Technology, which is used inside the mouse, requires the use of small prisms that emit light bundle up. This bundling makes it possible to read the movements even more precisely compared to previous methods. Because of the precision mechanics inside the mouse, I didn't want to open it so as not to damage it permanently. According to Kärna, this technology is also used in the military and is therefore fully developed.
The controller also processes a chip inside the Boomslang 6 MIPS (millions of instructions per second), which has the advantage that it can really process all signals from the mouse and no signals are lost just because the controller chip is too slow for the mouse. Most controller chips in other mice only process 1.5 MIPS. If you were to use a controller chip that can only process 1.5 MIPS in the Boomslang, the chip would slow it down because it cannot process the many signals that are sent to the chip with Kärna Technology and it would be just as imprecise as other mice. The controller chip must therefore be designed precisely for the DPI values of the mouse.
On the underside of the Boomslang 2000, small bumps next to the ball ensure that not too much dust can get into the mechanics. This dust barrier has been patented by Razer.
