I have a Halo (1st time round one) from smart parts. It is fantastic but over the weekend it kinda broke and I want to know how to fix it. It is the on off switch (the little black bit of rubber) When you press it now there is no reponse from it. You have to use a pen to turn it off or on. Anyone else encounter this? How easy is it to fix? I don't want to start unscrewing it as I know with my luck all the middle nit and complex feed system will come apart in my hands and my Halo will be reduced to a bunch of springs and plastic. CAn any one PLEASE help me out.
