A4Tech Bloody Gun3 UC3 Headshot V8 Gaming Mouse Review – $40 For The Ultimate Package

This one falls into the latter. Before getting to the results, the testing method is important to check first. As we can see, the program’s instructions tell us to connect two mice into the same PC – ‘A’ designating the Bloody V8 and ‘B’ defaulting to the other mouse (in our case the Cooler Master Storm Recon). It then tells us to hold both – one in each hand – and bump the buttons together.

You can note the problems right away. Firstly the two mice will be held opposite, meaning the left-click of the Bloody V8 will collide with the right-click of the CM Storm Recon. Even with the inclusion of MOBA’s, RPG’s, and MMORPG’s, gamers (and people on average who have not remapped buttons) will use the left-click more than the right-click.

Moving from mouse to mouse, psychologically the left button generally always feels smooth, more responsive, and less rigid than the harder-to-reach right button. Even though the two may be identical, perceptions and preferences (for right-handed gamers especially) lie closer to the left button than the right. Factor in extended use, wearing/rounding-out, and expected degradation – the left button will almost always ‘flatten-out’ faster than the right; so we can expect results to favour the left button and hence be slower on the right button.

Secondly, the program does not say how fast the mouse click is, but rather calculates the difference (faster by). Furthermore we have to assume by the picture that mouse label ‘A’ truly is the Bloody V8 and not the Recon (and vice-versa for ‘B’). Again while the program is unique, it is not very comprehensive since it relies on Windows which cannot calculate two simultaneous mouse clicks of the same buttons  on two different mice (and why would it?).

This means extra interpolation and extrapolation which would not be needed if the program was designed to be left versus left and right versus right (as a note both methods were attempted and yielded ‘failed’ results). It is not a big issue, but the Mouse Speed Test program does not go out of its way to develop a new algorithm; rather, it slinks around limitations placed on concurrent actions of the two mice.

The third and final problem is the human source of error. Since we do not have an automated system of pressing left and right at the same time, bumping the Bloody V8 and CM Storm Recon together has to be done manually which in doing so could favour one side/mouse over the other. With everything laid out though, we can expect the left mouse button of each mouse to be faster than the right.

This is exactly what happened after 20 trials were conducted – the first 10 with the Bloody V8 left button bumping the CM Storm Recon right, and the next 10 with the CM Storm Recon left button with the Bloody V8 right. As a right-handed user, the left button for each respective mouse is more ’rounded-out’ than the right, and as expected the Bloody V8 won the first 10, and the Storm Recon won the other 10. The results are tabulated on the side of each screenshot below and above.

These results were graphed to check the overall consistency as reported by the Bloody Mouse Speed Test program. Keep in mind that the test gives results of ‘faster by’, meaning that higher millisecond counts are better.

They are neck-and-neck in terms of numbers, as both have drop-offs here and there. Let us see which of the two reports as being more uniform:

On average the A4Tech Bloody V8 is o.72ms faster than the Cooler Master Storm Recon; however, neither mouse is steady according to the benchmarks. Perfect scores are those that produce a flatline pattern, and neither of the two mice do that. In terms of speed the A4Tech is slightly faster, but due to the wide range of numbers the conclusion is semi-accurate at best.

Tests aside the V8 handled very well during actual gameplay on the SteelSeries QCK Call of Duty Black Ops II Soldier Edition gaming surface/mousepad. As a gamer who plays on 3800 dpi, the maximum rate of 3200 dpi the Bloody V8 had no cases of mouse acceleration or faking dpi numbers.

Noting that and the fact that the mouse comes with no weight control, those who prefer low dpi settings will have no problem with LOD (lift-off distance) tracking, as the Bloody V8 prevents excessive tracking the moment the mouse leaves the surface. The cursor will literally stop when the mouse is a millimeter off the ground, and dare we say perhaps even a micrometer – absolutely astounding for a $40 mouse, as well as a huge reputation boost to the unorthodox ‘HoleLESS Engine’ design.


  1. Oh wow a new version of the hack mouse…yay. noob tool

  2. i have a bloody v7, same specs with this v8.
    i have to say, it’s the best mouse i’ve used so far.

    * previous owner of 3.5G DA and G400.

  3. I’ve been trying to track this thing down, but I haven’t managed to find it anywhere. Any word on where I can buy this thing?

    • Oddly, I don’t believe it is available yet. We got our sample a loooong time ago at the A4tech CeBit 2013 booth, so it has been a few months since then.

      If we get any news I’ll let you know where you can pick one up!

      • Thanks, I’d appreciate that! I’ve looked just about everywhere – A4tech has a website, there’s also a website for the Bloody Gun3 brand (where you can buy the software, but where there’s no mention of the V8 mouse). I’ve even sent A4tech an email, but I’ve heard nothing back.

        Oh, and thanks for the review as well!

        • You are right, they are quite hard to get a hold of, and that is primarily due to the language barrier.

          Luckily for us, Bloody USA will be at E3. I will be at the event in a few hours and will directly ask them about availability and any other questions/concerns you may have.

          Thanks again, and no problem. Glad you liked the review 🙂

          • Did you get a chance to visit their booth? Any word on a release date?

            Really appreciating your followup.

          • Hey there!

            Yes I did, sorry for the late reply. I went to the booth and was told a release date of Q4. I met the Bloody higher-ups soon after at a party and they said it is available now.

            Sure enough, it is:


            As you can see it’s on promo specifically for E3. They have refined the packaging and the mouse itself since I received it a few months back. This one has metal feet for increased sensitivity, but aside from that it is the exact same.

            Let me know if you have any more questions 🙂

          • Not a problem! E3 can be a bit messy, I’m sure.

            Looking forward to trying out the mouse in a week-ish.

            Your followup has been awesome, thanks!

          • No problem let us know how you like it!

          • So far I’m digging it. The software has some awkward English, but I like the way the mouse looks and feels.

            My only real concern is with the left and right mouse buttons. They hang over the bulk of the mouse, which makes me worry about packing it in a bag too haphazardly – it looks like they could break off with enough pressure. As someone who moves around a lot, this isn’t a minor issue.

            Other than that though, your review was spot on with every point. Feels good to finally have a good replacement for my old mouse.

          • Thanks 🙂

            As for the buttons, I took the mouse with me to E3 in LA. Went through the usual customs and rough handling. No complications whatsoever. As long as you firmly holster it in a bag pocket you should run into no issues.

            Thanks again for sharing!

    still just only 1 profile 🙁

  5. where can i buy this in japan?

  6. You know what sensor built in ?

  7. This obviously is a great mouse. However I believe it never took off be most gaming communities frown on these bloody mice. The clear advantage gained in games like counter strike is one of the reasons. Several streamers have been beyond ridiculed once people found out they had a bloody mouse and have since switched to other mice. Also this would never be permitted in any kind of professional setting. Many refer to this mouse as a hacker mouse. Which is an accurate statement considering there is technology built into the mouse to prevent it from being detected by servers where the mouse has been banned. One such feature is its dynamic PID. Another is the option to close all instances of the software where it notes specifically to remain undetected.
    There are also forums on cheat sites dedicated to providing profiles to compensate for recoil with each weapon in CSGO pretty much making the guns no spread when standing still.
    After reading their material it’s pretty clear they designed this mouse to give the player a significant advantage and can in more ways than one be considered hacking. People can spin it however they want but this is a mouse that allows you to cheat.
    I’m very surprised that nothing about this was mentioned in your article. Also they now give the software away with the v8 no longer requiring an extra purchase. They must of figures that the type of people buying it would easily have access to ways of cracking the software and was probably cheaper to give it away rather than try and keep it protected against today’s software crackers.
    Either way this was an excellent review. I was very surprised to read just how good of a mouse this actually is. I think there assumed demo is just a little bit below board and that is what ultimately prevented this mouse from being more commonly compared to professional gaming mice.
    Cheers. Sorry for typos. I’m on mobile and driving 😉
