I was given the IceMat last Christmas as a gift that I had said I would rather like... the reason mainly being that I would not be prepared to spend the £27 that I think was the asking price at that time (inc. tax and P&P).
However when I received it I was immediately fairly impressed - it has a cool look and feel right out of the box. By the way when you do open it try not to loose the little sticky tape section you get - although it is not obvious what this is you will later discover there's an insert explaining it is Teflon sticky tape for your mouse feet (and if you chucked it out with the box this could be annoying!)
Next - size... this is NOT a large pad for those of the sweeping gestures - 24.5 x 20.5 CM as I measure it. You might notice from my pics that I have VERY cramped triangular "nook" for my workspace though - so for me a small pad was almost essential. The third pic is trying to highlight the bevelled edging of the pad which is very helpful in the ergonomic feel where your wrist is liable to rest. It is also nice having a cool frosted glass surface near your hand whilst working I have noticed. Lastly it looks pretty cool!
Prior to the icepad I would consume maybe one a year of more regular pads as the surface would deteriorate and, more significantly the edges start to ride up and curl under my wrist. This is a thing of the past with the icemat!.
NOTE OF CAUTION - Icemat is definitely fine with regular and Laser mice (that's my MX1000 you see poised upon it!) BUT be careful about optical. Why? Well although it is frosted and opaqued on the reverse which the makers claim makes the pad IDEAL for optical mice I have found by personal use that it would not immediately track my M$ optical mouse. I think the reason is that the optical field is farther away (as though your mouse were on "stilts" if you like!). In my case it was very very annoying, but I DID resolver the problem by cutting off the small feet that M$ mouse had and replacing with the Teflon tape. Others may have to improvise in similar fashion if using optical mice. I did send an email to the IceMat site - no reply whatsoever, so thumbs down there.
I cannot comment on suppliers etc since this was a present and someone else took care of that.
Last comment - use with the MX1000:- well this is like the "dream team" for me with mouse useage - ultra prcise, highly controllable and responsive, feels totally smooth, zero mouse wobble (some may find their MX1000's can come with one i have heard, and was aware if anything would show up such a flaw the IceMat would be very unforgiving).
So in summary - recommended to those that want a regular size mat for a lifetime and are liable to go with laser technology mice.
