I think the Cera LL without a latching switch is a non starter. I own one and am very disappointed that one will not be supplied. I can understand if they do not want to supply one prospectively due to liabilities real or imagined, but it is up to TET to make that decision. Whatever they decide we will have to live with. I don't think they will be taking back used units for refunds. It might lose them some orders, but it's their bed to make and sleep in. I wish them luck. I wouldn't have ordered a Pax, if I had to hold down a button to get vapor to come out.
