I bought this product in September as I have lots of problems staying asleep. I bought the light weight cover For the summer and also the velour cover for colder months. Success has been erratic but I think in general my sleep has improved. I do find it difficult to fit the covers, the light weight one needing to be tied to the blanket and the velour one having press stud ties. For someone with a back problem and also carpel tunnel syndrome in one hand this presents me with a real problem. The press studs are definitely easier to use and I would have preferred the other cover to have the same. The other problem I have is shaking it each day because of the weight, I don’t have anyone to help so it’s a real struggle and I end up having to shake it from all four sides to get it even. If you have strength issues you may need to think twice before buying. Plus and minus points as with everything but for me it’s 60/40 in favour.
