I bought this a fraction too late as the very hot weather had passed after this arrived. However, it definitely does the trick - just placing your hand on it you can feel how cool it gets. I did notice that the magic gel inside isnít necessarily distributed evenly so the gel is mainly within the centre with limited effectiveness towards the outer edges. This may even out over time as your pet lays on it and forces the gel to move about. I bought this for my cat who, although would sit on it, hadnít quite learnt to fully lay on it when he was hot so it may take a while for your pet to get used to it as it is a different type of surface to lie on that may be unfamiliar to them.
Also worth noting that although described as an XL size, I wouldnít necessarily describe it as XL so you may want to double check the sizes to make sure itís big enough for your pet. As I had bought it for my cat, it is plenty big enough for him (even though he is a larger cat).
Worth noting as well that as this mat is clearly intended for dogs, the matís surface is not immune to cats claws - I have had to patch a hole with gaffa tape where my cat stretched and pawed at it. I was fully aware this could be a problem so thatís not a fault of the mat necessarily.
Recommended - it clearly works as described but may take a while for your pet to get used to it. Not necessarily ideal for cats sharper claws so extra care may be required in this instance.
I purchased 2 very reasonably priced cooling mats and was impressed by the soft padding ( greyhounds are very bony!) and immediate coolness to the touch. Hounds were very grateful for them during the recent spate of hot weather. The mats even functioned when scrunched - greys like to scrape around to arrange their beds. Would definitely recommend.
