Thanks for reminding me to update here .
Got the lowest level one about week or so back.
Have been using it most evenings .
i started with keeping a t shirt on . I do it on the bed as apparently that’s less pressure.
I didn’t feel much with the t shirt so took it off half way ( I do 20 mins ) but it hurt and I stopped.
I then kept going and found I got used to it so now do it without t shirt . It feels quite warm and after a while doesn’t feel painful. You have to be careful not to forget else it does hurt.
i am not quite sure what it does. It does feel relaxing after . So far not helping with sleep. I will keep going,
they do have various offers on at times and also discounts for new shoppes. I think they also have a money back guarantee .
i need to look into whether it’s cumulative, it works more the longer you do it .
