Yes, I would say Travis, first of all on the demand in the training component, we’re in very good shape, I think we've got the right cues, and again we've talked about all along with roughly 50 sales folks. We have a very targeted focus, we're not trying to hit all accounts and all areas. And so from that standpoint, we’re very well aligned and properly funded and that's a big chunk of some of the investments that we made in the first half of the year, both reimbursement, as well as training of clinicians and our sales teams. As well as their reception for those that have used this point has been very good, I mean, we have cases of products being used on DFU’s that weren't healed by other products that have actually performed well using the Omnigraft product, and so we again very much aligned to what came out of the clinical studies, which is no surprise what we got expected. As I mentioned, I mean it is summer months, you know the story on value assessment communities, many of those are used as a control point for IDN’s in big centers, makes a lot of sense, the approval process and sometimes if the agenda is filled in August, you don't get on until September to have your case laid out. And I think we were a little bit over optimistic that we could get through some of these a little bit faster, but that's a small setback relative to how we think about things, I think the bigger point is, it’s received very well, teams well trained, doctors are excited about getting our hands on it. In fact some of our investigators haven't been able to get the product yet this is just getting through their backs as we speak, and so they’ll be starting use within August and again just part of the process that’s evolving really within overall healthcare and value assessment communities, but it’s doing quite well and I’m as optimistic as ever about potential for this product.
