This is an excellent product. I have been testing this for more than five days at home before taking it out. A day after receiving this I also got the mattress Trekology ALUFT UL 8O Ultra Sleeping Mat and comments on it will be posted on its page. Firstly, I live in Sydney where our cold temperatures are not extreme. I hike and camp out for few days at a time and always used a sleeping bag and this is the first time I will be using a pillow and a mattress; hence I can’t compare with other brands. This cost me only A$ 2O. This does not take more than 5 full puffs of breath to inflate to make it harder, 4 make this moderate. Air value is strong and well-made and practical. I am not a tall or heavy person and a side sleeper. For me 4 breath did the job and tested for 5 consecutive days and did not deflate at all. It felt very soft and have an elastic strap that could be strung around the sleeping mattress hence it stayed in place. Yes, it is another great Made in China affordable product, with excellent material and workmanship. Hope it will last for few years, at least 2 to 3 years will do the job for this as nothing forever.
