First, the price is nice, if it were $10-15 more I would rank it a 3, as in, "it's okay" or better but a bit too pricey for what it is. However, at this price, "I like it" a lot. If it is durable it may earn my "I love it" -- especially since I will probably use it pretty hard (8-12 hours a day, in and out of a laptop bag nearly every work day), and since it is a $15 mouse I won't be all that careful about it.It is my main mouse for a desktop replacement laptop, both travel with me to work most days. So, I will see how it holds up and update if it wares out or develops problems - if I don't update that means that it is still going strong and I still stand by this review. If it lasts into the 5 year range I will update and probably change it to 5 stars.Next the review points:Pros:To start, I like this mouse. It feels good in my medium-large man hands. The grip on the thumb side feels good; although, I had to push mine into place as it was peeling on arrival and it continues to be somewhat loose or prone to getting pulled out of place, it sits to high above the surrounding plastic [Edit, this continues to be "loose"]. (I do wish there was a thin strip on the pinky side.)The adjustable DPI will probably be nice for some light game play and some situations, but I generally just keep it on the lowest setting. But having the option is a bonus.The mouse is nice and responsive and I have not noticed any lags (I'm using it on an Ivy Bridge I5 3230m in a Toshiba Satellite L series, Windoze 8 and will be dual booting Kubuntu, when I get a chance to set it up; if I don't update the mouse works fine as a native in Ubuntu as I expect it will [edit, confirmed, works in every distro I've played around with lately (all Debian/Ubuntu forks)]).The back and forward rocker works great and is also very nice to have.The mouse moves smoothly and works on every reasonable surface I've tried it on, including the number pad on the side of my laptop keyboard, which is nice.Range is good, as advertised about 15 feet through walls, etc and about 25 feet in the perfect situation (in the same room or outside).Cons:I wish it had a real off switch since it wakes the Laptop up on button click, until the mouse shuts itself off; you have to take the dongle out when you are transporting the laptop or shut off the wake up settings.This boarders on nitpicking and is related to the previous point: I wish it had a clip like some Logitech mice do so that it clips to the back of my screen and when clipped it shuts off the mouse so that it doesn't wake up the pc -- [edit, I really, really wish that it had such a clip]. This is a good thing because it protects the mouse by ensuing that it is in the padded case with the laptop, rather than just thrown into the bag or outside pocket to get banged, bumped, and (maybe) broken. I really don't understand why anyone would manufacture a wireless mouse without this feature. It just makes good business sense and is relatively cheap.Finally, the mouse does feel a bit less high end. As I mentioned the grip pad for the thumb was out when I took it out of the box, but other things don't quite fit right. One corner of the battery cover sticks out and is a bit stiff to remove (feels like you might break it), but hopefully I'll only replace the battery ever year or so.Overall the mouse feels just solidish. As in, somehow I suspect it isn't as durable is my partners beat up 3-4 year old Logitech that is still going strong. But only time will tell and that Logitech was almost twice the price.Nit-picking (in order of importance):The scrolling wheel is a little high and I wish it was closer to the tip of my middle finger.This boarders on obnoxious nitpicking, but the material you touch is that slick glossy plastic and I wish it had a bit of texture.The slick material feels, sweaty or something, I don't know, I don't like touching it as much as other mouse textures -- yeah, it is nitpicky, I know.At this point I strongly recommend this product. I like it a lot right now for its price, but if it proves durable that may make me love it (as in 5 stars).If you are a cheap-skate like me and looking for a good mouse, I think this is it. If you are a high-end type, this isn't it.I will update when the battery dies, currently it has one AA Eneloop that was fully charged when installed.[Edit, a month after purchase, I like it okay, but I think the 4 stars will stick and I very much wish that I'd gotten one with a off switch and/or a clip -  I would've payed $10-15 more for these things.]
