A4 X-748K Gaming mouse 3200 dpi/USB

Straight to the point:1) The mouse is good, quite good infact.2) 3 usual buttons + 2 side buttons (usual back and forward in browser) + an extra button + a illuminated sensitivity button + 7 little weights.3) The scroller is nice n quite, unlike some other mouses.4) 3 extra buttons can simulate any keyboard keys in games when customised.5) Nice dark discreet design.---------------------------------------------------------Few minor bad points:1) I like things to be fresh, however my mouse had small scratch marks at the top, which meant somebody has tampered with it (quite annoyed by this).2) 2 side buttons dont seems to work if provided software isn't running, however the software is really good and doesn't noticably use up processor time.3) For some reason when viewing a PDF file in adobe acrobat, the scroll jumps a few pages when provided software is running, just close it down temporarily and you should be fine.---------------------------------------------------------OVERALL: Still a very amazing mouse, i'm enjoying it a lot, happy with its low price.

Simply put, it's a very good mouse:- first of all: it's VERY comfortable: the ribbed rubber pad under your thumb makes it a pleasure to hold this mouse.- buttons have very distinctive clicks, easy to click- side buttons are placed somewhat too high, so you will have to move thumb from normal "relaxed on the table" position to hit them, but with practice I started to keep thumb below them and "roll" it to these buttons without loosing mouse grip. Try it - and clicking these buttons will become quick and easy.- "third" button in the middle is easy to reach and click (with my large palm)- never used the DPI button: used (provided) utility to set it to disable DPI switching and no blinking, so it doesn't distract.- heavier than an average mouse with all the nuts in.I bought mine in 2009. Now is 2012. Over three years:- place under little finger is polished and non-slipping surface is wiped out (who cares?)- ribbed rubber pad under thumb is now polished (who cares?)- gliding feet (stickers at the bottom of the mouse which make it glide, and spares of which you will get in the box) are still in place and I'm not planning to replace them. (I use mouse on a mouse pad all the time: heavy, thick rubbery base with cloth top surface)- the only downside is that recently the right button when pressed at the very far left edge, started to slightly "stick" to the central bit of a mouse (where the wheel is), what makes it harder to press than to release, making overall performance lower, clicks less distinguishable, and harder controllable. So, meanwhile I just click any other place of that (large!) right button with no problems.I expect the issue with sticky button described above to progress, so I've just ordered this mouse again (while it's still in stock), so I have a replacement the same day as I declare my first one dead. Having that it already survived three years of very active use, and was very comfortable throughout this time, I am very happy with the purchase. Highly recommend it!Other mice I used: Logitech mouse from Desktop Comfort combo, Logitech NetScroll+, Microsoft IntelliMouse Eplorer for BT, various HP and NoName mice. This one beats those all in comfort.UPDATE as of 21 Apr 2016: the first mouse which I bought back in 2009 is still running well. Yes, it looks worn. But it works perfectly fine. Right button sticking went away after a clean up.

Let's get straight down into the review, and talk about the feel of the mouse itself. Coming from a cheap (very - £3) mouse to this one was a little shock to the system, simply because of the shape. I imagine that most gamers would have no qualms with this, but my thumb was too far up the side of the mouse originally to be comfortable. After getting used to it, it makes perfect sense that the side-grip is positioned where it is, and then the right side of the mouse is surfaced with the same matte slightly-grippy material as the back to provide just enough friction for your thumb and hand, respectively, to stay put.The main two buttons have a good physical response that is clean and crisp, and the scrollwheel push is on the same par, also producing a smooth, quiet scroll. The side and front buttons (three in total, two and one resp.) are placed in reasonable positions and are programmable by software downloaded from the web site or from the included CD, and these are then uploaded to the mouse and can be ported from machine to machine. Currently whilst playing COD4, my front is weapon change, and my sides are reload and grenade. It's handy to have common tasks like these very close by. The side buttons are also textured differently to allow distinction between them when you're looking at the screen instead.I actually removed all of the weights included with the mouse, as I'm used to a light one. But if I recall, there were around seven weights to remove from the cartridge. Even with these left in, the mouse glides very smoothly across a Qpad mat.Resolution change is easy and software-less, just by using the coloured button below the scrollwheel. The colours of this button can be also modified with the programming software, as can the DPIs themselves. I'm running on 1600dpi, simply because it provided the best consistency across all applications. In my opinion, pushing it to 3200 is overkill, but it's nice to know the option is there.Final comments on this would be that I don't recall having any tracking issues with this mouse. As mentioned I'm using a Qpad, but the laser and its housing looks of good quality, and is horizontal not vertical, for those interested. Overall this is a very solid product, and one that has provided a huge improvement over my old mouse. I can't compare it to any other high-end mice, but even in fast-paced games it's surpassed expectations. Five stars.

Llevo 2 años con este ratón y me va fenomenal. Lo compre para jugar a BF3 y cumple perfectamente el propósito. Me esta dando fallos ahora por el cable que tras 2 años de uso, doblándolo para guardarlo etc tiene un corte en la conexión. Por mi confianza en el producto he decidido comprar otro igual pero de mayor DPI (3600) en vez de 3200 que tiene este. El software (Oskar) que viene incluido parece bastante útil para generar macros etc aunque no lo he utilizado.

Habe vorhin meine 11 Jahre alte Fireglider gegen diese Variante von A4 Tech eingetauscht.Im direkten vergleich fällt mir nur das Kabel als wirkliche verbesserung auf, weil diese jetzt elastischer durch den Stoffbezug ist und sich besser in der Umgebung anpasst.Mir fallen auf jedenfall sofort die negativen Punkte auf und das wäre einmal die doppelte Lautstärke des Mausklicksgegenüber der Fireglider und der 2mm große Spalt zwischen den Tasten (über den schalter für die DPI verstellung) und weil ich das Licht in der neuen Maussoftware nicht ausschalten lässt obwohl das layout Identisch ist mit den alten Editor... scheint es grell aus dem Mausgehäuse heraus und kann einen schon mal ins Gesicht leuchten,wenn man die Maus richtung gesicht dreht... und dreck/staub wird auch seinen Weg reinfinden, klar war die alte Fireglider auch kein Paradebeispiel aber trotzdem geht das schon richtung pfusch.Da die abtastung optisch stattfindet und nicht auf eine Lasertechnik basiert, dürfte das Licht aber nicht schädlich für meine Augen sein, oder etwa doch? Vielleicht kann mich da jemand aufklären der mehr ahnung davon hat.Chinaplastikgeruch nach dem öffnen ist ja standard alles halb so wild, solange es nach 2 Tagen nicht mehr gammelt.Hauptsache ich bekomm kein Krebs oder Corona :DAbgesehen von meiner Kritik zu den oben genannten Punkten scheint die X-748K soweit ganz passabel ihren Job zu erfüllen, aber ich hätte lieber nochmal die alte Fireglider gehabt, denn das Kabel wiegt die anderen Problemzonen nicht auf und ich glaube auch nicht das die Maussoftware von 2013 nochmal geupdated wirddamit man auch das Licht raustellen kann... echt schade.
