Ok so apparently it isn't DPI, it's CPI.  The second highest rated acronym on acronymfinder.com for CPI is Characters Per Inch, and this is what comes to my mind when looking at the abbreviation.  Another meaning for CPI is the Couch Potato Index, which I'm guessing is the severity of how much you are a couch potato, haha.  Anyway, in this case, I can only assume it makes sense in Polish.  Ok, well who really cares right?  The four settings on the mouse are obviously DPI and each setting is chosen by the side up/down button.

At the lowest setting of 400 DPI, the indicators are all off.  Then when 800 DPI is activated by the side button, the lower LED is lit up.  1600 DPI lights up the middle LED, then 2000 DPI lights up the top one.  The LED indicators are blue and are visible from pretty much any angle (180° semi-sphere).

If you are used to a Microsoft, Logitech, Razer or any brand of mouse that has more than 3 buttons, you are probably familiar with the "forward/back" buttons on the left side, where your thumb would be if you're a right hander.  I use a Logitech MX518 and a Microsoft Intellimouse Explorer 3.0, and have been using the side buttons for forward/back navigation for years, especially in Internet browsers, and also make use of these buttons in games.  So having these buttons as on-the-fly sensitivity controls on the ML-903 is handy, but also slightly annoying as you can't configure them to be anything else and I find myself inadvertently changing the DPI whenever I want to jump back a page, use the flashlight in a game, etc.

Get into the groove

The concave section just under the on-the-fly CPI/DPI buttons is a bit too concave and the side of my thumb ends up resting on the CPI/DPI buttons.  This just feels awkward and seems as though the mouse has been designed for people with smaller thumbs.  I do have large thumbs, 28mm at the widest point, so this probably won't be an issue for most people.  As Lognetmedia have effectively designed a Logitech clone, I don't mind comparing it to my MX518 so much.  My MX518 is a lot less concave in this area and by big old thumb rests on a fairly flat surface relative to the ML-903's half-a-pipe level of concavity.

Scroll wheel

The scroll wheel, handy for scrolling through long webpages and documents.  It is often used in games to switch weapons and can usually be keybound to other game controls.  I've found scroll wheels vary quite considerably and can make the difference between a good mouse and a great one.  My Logitech MX518 scroll wheel is easy to scroll up and down, and has a very positive stop/start when it advances to the next notch.  The Intellimouse Explorer 3.0 is as easy to scroll as the MX518 but the tactile notching effect is not as good.  The Lognetmedia ML-903 has noticeably more resistance to scroll than either the MX518 or Intellimouse and the notching effect is about the same as the Intellimouse.  It's not particularly stiff, and it may work itself loose over time, but it just seems a touch too much effort to move it for a gaming mouse, especially given the weak notching.  If the scroll wheel isn't easy to move and the notching is weak then it can be hard to use in-game for something like a scope zoom for example.  Scope zoom could cycle: Off -> 5x -> 10x, and you could find yourself overscrolling because of the slight extra effort and the weak notching.

Human auto-fire

So the claim of "80 clicks in 10 seconds" seems very optimistic, but after using this mouse in many games and applications, I think this rate of clicking would be possible if you had almost super-human clicking abilities.  That is to say, the primary and secondary mouse buttons have a "hair trigger" response that require less force than my Logitech MX518 or Microsoft Intellimouse Explorerer 3.0.  This proved itself useful in Rainbow Six: Vegas when I had one of the weapons on single shot rate-of-fire, with a silencer, and needed to take out a few enemies at once.  It certainly shone here as an incredibly accurate and lightning-fast mouse for first-person shooter (FPS) games.

As you know, the mouse wheel also functions as a third button if you press it down.  The ML-903 has a bit too much resistance here and I found myself mis-clicking the middle button (i.e. not clicking at all because the mouse requires more downward force than I'm used to).  This seemed a bit odd compared to the hair-trigger main buttons, but I can understand that if it was too easy to depress, then you would end up inadvertently pressing the middle button when scrolling.  I still feel that the middle button should be easier to press though.

Slip-sliding away

Polytetrafluoroethylene, more commonly known as PTFE, can be used to make low-friction pads or feet for computer mice.  When coupled with a low-friction metal or plastic gaming mousepad, the mouse can glide effortlessly over the surface allowing very fluid and accurate movement.  The ML-903 makes use of these feet and it works.  It's noticeably easier to move around than my Logitech MX518 although that might be because the pads on the Logitech are fairly worn.  Regardless, the non-slip feet do a fantastic job for Lognetmedia's mouse.
