Certainly. Hello, Andrew. This is Steve. I think that the challenges have morphed over a period of time. Initially, we had challenges I think with the technology. The element of footprint, the cost requirements that we felt where necessary to drive mass adoption in the consumer markets. These elements, I think required additional time and effort in order to get them to the point where they are today. Today, the technology is baked. It’s solid, it’s at a price point that is viable for mass adoption, it works across the number of verticals, it’s easily integrated. It’s been proven very, very reliable. So, I think we’ve passed that juncture. I think the next issue that comes to bear is really engaging with the customers. We are a bit surprised, but there is – I will tell you that there is a bad taste in the number of our customer's mouth as it relates to wireless power. As I mentioned, and I was very specific about this in the call that every one of our top tier customers either has, had a first-generation product or has attempted to release one. And they were not successful for one or more reasons. As an example, one-off our hearing-aid vendors recalled over 30,000 units, the entire first element of the shipment because of the position independence problems associated with the first-generation technology. So, we’ve had to overcome, I think some of the problems associated with the first-generation technology and this has resulted in very, very significant and extended testing times along with extended market research. I think we’re also coming to the end – if it hasn't ended that phase. Right now, the long pole in the tent quite frankly as regulatory. We – as we have engaged with the top tier consumer electronic companies, they are looking to launch on a global basis, and even if they launch regionally in one or more of the key regions they are looking to have assurances that they can launch on a global basis. And so, I think this is really the element that we’re focused on right now. And why I say that it’s all coming together we believe that late this year, early next year we would have paved the way for global launches across all of the major regions. We will certainly overcome, I think the additional testing and first-generation problems that we’ve had to deal with and as I said, the technology is baked. And so, it’s taken us a little longer than we anticipated, but I think we are converging on what we believe will be a very strong exit to the year and a real break-out year in 2019.
