A4Tech V7 Detailed Features
HoleLESS HD Engine
One of the first things you may notice when turning over the V7 is the lack of a sensor hole anywhere – not to worry, as A4Tech has made sure to describe on the bottom of the mouse itself it is just a feature of the HoleLESS engine. As far as I can tell, it is simply a tinted window for the sensor. Simple, but incredibly innovative. After the issues my Razer Lachesis (with the 4000 DPI) sensor had with any speck of dust or thread getting in the sensor hole, this simple change seems long overdue. Perhaps it only works with optical sensors – in any case, it is one of those features that makes you wonder why no one has done it before.
It may or may not be a result of the HoleLESS engine, but the sensor performed flawlessly throughout my testing. I was surprised to find it functioned perfectly on the glass top of my desk, as well a Goliathus Speed Edition pad and Destructor hard pad. You shouldn't experience any trouble finding a surface on which to use the V7. It reminded me of the flawless performance I experienced from a Razer Death Adder when they were first released. The polling rate was similarily solid - testing using a direct input mouse rate tool, along with a mouse rate checker utility showed the 1000 Hz polling rate to be as claimed.
6x Shooting Speed
On the packaging, the V7's marketing team wants to ensure you don't miss out on any features – one of which is the claimed 6x faster shooting speed. As gamers, we'll take every millisecond we can get – and if the claims are true (most mouse buttons activate after ~18 ms, whereas the V7 will register a press after only 3 ms) that ~15 ms difference might determine if your input gets placed in the current outgoing frame of action or the next. While testing that specific circumstance is outside the scope of this review, A4Tech provides a mouse click speed test that you can use on whatever set of mice you would like. It just so happens I have a group of Razer mice standing by to test against.
You can see in the screenshots I followed the testing procedure described in the software program – you simply activate the program, then press the left mouse button of mouse “A” against the right mouse button of mouse “B”. To the right, you'll see the results. I tested each mouse three times, then switched “sides.” Finally, I tested two Razer mice against each other – it seems the results were pretty consistent and back up the claims made on the V7 packaging.
Then the V7 (again starting as Mouse A then switching halfway through) vs. the Razer Mamba (again in wired mode):
