Decent, good even, but not perfect and does feel a bit cheap

NB: You want to know the DIMENSIONS of this mouse? Read on... they're in my review.
I purchased my M557 from another reseller than Amazon, because Amazon did not have it in stock at the time.
Overall I am pleased with my purchase. I use four mice concurrently, including this one, on various computers, PC and Macs (the other three are the Logitech Anywhere MX, Logitech M318e and Apple Magic mouse, and I mention them because I will make comparisons where approriate). This particular mouse was intended for use with a Mac Pro, where I wanted to free up a USB port that was occupied by the Logitech Unifier used for my Anywhere Mouse MX. My first bluetooth mouse ordered for that purpose was the Apple Magic Mouse, but the Apple mouse does not work for me due to its anti-ergonomic(TM) shape.
The M557's main selling point is obviously that it is a bluetooth mouse. As such it works very well, connecting very quickly to my Mac Pro and maintaining the connection well. It also works immediately after waking the computer from sleep. I have only tested it on this Mac, not on any PC.
So full marks for the bluetooth implementation, on Mac at least. Another good point is the left and right buttons, which only need a very light press to trigger a click, which I appreciate.
Like all battery powered mice that use two batteries, the M557 feels a bit weighty for its size. In that it is very comparable to the Anywhere MX, probably lighter but not by very much at all. You may like this weight, or not. I like how it feels. If you want to get an idea of the weight just hold two AA batteries, that's almost the weight of the M557, because it feels featherlight when the batteries are removed.
Tracking is reliable on the few surfaces I've tried (I have not tried glass, but wood and fabric).
So what's not to like?
Firstly, the M557 is all hard plastic. The top of it is very pleasantly smooth, almost like a touchmouse, which this one isn't. But the sides are also hard plastic. There is no rubber to make the grip more steady and pleasant, just some less smooth hard plastic. Compared to my other mice, only the Apple Magic Mouse feels worse, not because of materials though (the magic Mouse is all aluminium under a very smooth glassy top), but because the Magic Mouse has the most awkward shape of any mouse I've ever tried in my computing life, so it's not hard to design a better one! This overall plasticky feel of the M557 is by no means a deal breaker, but definitely a disappointment. Both the Anywhere MX and M318e (my other Logitech mice) fare better in this respect, despite the M318e being a substantially cheaper mouse than the M557.
Secondly, the scrollwheel has that awful ratcheted feel which, to be fair, may suit some tastes, but that I thoroughly dislike, being used to the smooth scrolling Anywhere MX and even M318e (which lets you feel some ratcheting but very lightly, and still has some freewheeling action). With the M557, the wheel stops turning abruptly as soon as you release it, no matter what speed you use it at, giving it a very obsolete, 20th century feel. Not at all natural when you are used to freewheeling scrollwheels or touchmice, touchpads, Android touchscreens and the like.
The scrolling speed can by controlled by way of the Mouse Preferences in Mac OS (somewhat strangely, as it does not appear in the Logitech Control Centre), so all is not lost. A high scrolling speed can be achieved, but the action still feels far less smooth and pleasant than I would expect on a modern mouse.
Now a bit about the software:
The Logitech Preference Manager provides the usual control over what the various buttons do. On Mac OS the two centre buttons (the scroll wheel press and the square button) can be assignedd to trigger Mission Control, Exposé, Smart Zoom, Launchpad, Lookup or "Middle button", which I'm not sure what it does. The tracking speed can be increased beyond what the general Mac OS Mouse Preferences are set at, which is nice. I use two 24 inch screens and can glide between the far ends of the two monitors with my wrist resting on the desk, and yet if I move slowly I still get precise responses. Very well done.
Finally, here is some critical information that is often missing from commercial webpages such as this one, and that should always be taken into consideration when choosing a mouse for your hand, the ACTUAL SIZE of the mouse (not the packaging!)
Please understand that due to the mouse's shape these dimensions are approximate. It's difficult to hold a metal tape measure against a curvy object and get accurate readings. But they still should help you decide if it should fit your hand, as this is so down to personal preference:
Length: Just under 100 mm, measured from the front to where the top ends at the rear (the base is much shorter).
Width: Up to about 57 mm, fairly constant along the length of the mouse. This is an approximate measurement at the top, the mouse is narrower at the bottom.
Height: 34 mm (that would be at highest point of the "dome", where the bluetooth logo is located in the middle of the mouse, and is only as precise as I can get by holding a tape measure to the side of the mouse and reading through my glasses with my poor eyesight. It's obviously not as high near the sides).
It's not a mouse that will give much support to your hand unless you have very small hands, but it still provides adequate occasional rest for my mid-sized male hand. It's good if you use a light grip and move your mouse with mostly finger action and a little bit of wrist rotation (and probably a high tracking speed). Mileage may vary.
I am pleased with my purchase. It says a lot that this sub-£35 mouse is going to be my favourite for my Mac Pro, when pitted against a £60 Apple Magic Mouse (erm, perhaps it says a lot more about the Magic Mouse's awkwardness though, than about the M557). You will probably not regret your purchase if you get the M557. Just don't expect too much, it may be one of the best bluetooth mice around but if you don't need or don't prefer bluetooth, then there are plenty of better mice with rubber grip, ergonomic contouring, freewheeling scrollwheels and such.
My plan is to use mine alongside the Apple Magic Trackpad, to get the best of both worlds, traditional pointing device and multi-gesture touch device.
