I ordered two of these pillows for my queen bed.  I have slept on them now for a couple of weeks and they are still as full and firm now as they were new.  Most pillows flatten some by the second week.  The cooling gel does help keep my face cooler while sleeping on my side,  I like the fact that if you prefer a little firmer pillow you can turn the gel side up, but, if you prefer a softer pillow you just flip over to the memory foam side.  I started using the day they arrived and I noticed no smell coming from them.  I am going to buy four more to put on my guest beds.  Good price also compared to some of the other brands.  Buy them, you will like them.
