OK, after popular demand
here is the Dreamgenii Pillow first night update! 
Well after a sweat filled night (my god how hot and humid was it???) and a morning of nightmares about the world tipping and having to climb cliffs to get away from the rising sea and sharks (OMFG!!!) so far the pillow has been positive. I had to chuck it half way through the night because I was just too hot and couldn't cope with anything touching me, but when I was using it it was really comfy and felt supportive lying on my side. 
So far so good. I am going to sleep downstairs on the sofa tonight (where it is about 10 degrees cooler) and try it again and hopefully will be able to keep it with me all night.
It was certainly a massive improvement on the Mum E Pillow I bought a while ago, which is HUGE and bulky and took over the whole bed and gave me neck ache!!!
Will update again tomorrow after hopefully a cooler night's sleep....
