If you wish to cancel or change your order, he accommodates quickly.
I ordered a Hi CRI Rotary in January, and changed to Hi CRI Clicky in May.
He doesn't send updates, and I understand he doesn't send shipment notifications, but if you eMail him a question he gets back to you quickly (same day for me, every time but one,) and answers to the best of his ability.
I really want the light. I could wait with money in my pocket, and place an order when they come available, and hope they aren't snapped up before I get mine. Or I can wait, with money in Henry's pocket - so he is assured of demand for his light, and has needed funds to procure components and supplies - and then I get one when they come available.
I chose option 2.
I haven't seen stock on Hi CRI's since long before I placed my order.
