Half way through a tub of this. I was wary of ordering but the quality of the 'platinum' seems higher than the regular Grow products. For me it's a nice light 'background' daytime that certainly has it's place, but sadly not at £8.50.
I have this on on hand most of the time. For me it is great for slowing the pace right down if I need to hit the brakes during the day, sometimes to a complete halt but not feel sedated.
