So, Mini, here, this is Duane. I will tell you, if you too, the two biggest complaint that we are having at the moment, which is pretty simple is, I want it and I want it now and I don’t care what the insurance says, because and like I said, that’s all being triggered by the fact that we are doing this for free and we try to explain it soon. And the second, the second piece is, as soon as we started sending out notices for the first group of people. So people that were eligible for reorder in June, send the notice out, because we are looking at their insurance, with just help everyone on the call. The way we decide to get upgraded, as soon as we have to manufacture one, we said, okay, who is eligible for reorder in June. Who is eligible for reorder in April? Who is eligible for reorder in May? And so you use that is a trigger. As soon as we sent out that first batch, what we ask patients to do is, go to the website because there are differences in the particular product this one versus the other, how you started up, obviously you get to get the new - you get to use the PDM, don’t use the old PDM with the new product. It all seems relatively simple. What I will tell you, as soon as word went out, but we started that conversion, everybody in our customer base. I think call because it’s for free, right. So in [hinesack] I think long-term it’s absolutely, we are doing the right thing for the patient, we are doing right thing to everybody. But it was like a tidal wave that rolled in here and our average length of our phone calls are going up, we get people calling up and saying, I want it, I want it now and we’re saying, you are not eligible for reorder until September and they like I don’t care, I walk in, I want it now. So, I would tell you, I’m not sure what we do differently, I’m still trying to work through that. But I think the only complaints that we’ve heard is our customer service, our customer service lines are been jammed solid, we have doubled the number of people, we are answering the phone calls and we are starting to make inroads into all that. But, that magic word, free, has triggered an avalanche to us, so.
