Very nice product. it works well for cooling my laptop when I am gaming. It is easy to freeze and when frozen it is still easy to manipulate. it absorbs alot of heat and is long lasting. looks like it can take alot of abuse since i have been freezing and cooling it about 20 times with no performance loss seen.
