Well, I would assume NOV is out there doing something with upgrading their ideal rig and trying to take their technology and put it into a land rig. I think there is no question that technology that factor is going to exist in this sort of place. We're repackaging it to be cost effective on land. I think it's the key. And I think one of the differentiation of Nabors' strategy is this SmartRig platform that we are creating will be able to be the rig of the future. Each one of these far rigs was designed, as I mentioned at the Analyst Day four years ago with the view that there is the last stage of the last mile completed, the less mile would be -- with the four automations. And so, the rig is also up to accommodate that. So, instantly when we make this available in scale, we would be able to roll it out, and I think no one else has that, and these are our leading service company. It's also high rig of future. Once they design they have to build them, they have to build a hundred of them. Whereas today, we have a hundred rigs and we can just retrofit and the time to market is going to be a lot shorter. So, at that point of view, I think we are in a unique space. I think from a technology point of view, I think we have all the ingredients, and as you saw at Analyst Day we had the prototype of the eye-racker, we are shaking it down, we are actually making some changes to it. We will start in the second half with getting some customer responses of it. And like we said our goal is by the end of the year to really be commercial with this prospectus scale. And on the NDS services side, that aspect of it, again, I don't -- as far as we know, there is not other people thinking about it the way we think about it, I think frankly, the score now for everyone whether this is causing to putting the NDS service in the rig make sense. I think some of our competitors don't believe in it at the strategy, and they don't think operators will be open to it, or it's too hard, et cetera. So, it truly will come to us to make sure the strategy works and to prove it up. I think I am encouraged by the fourth quarter numbers, as you heard, you know, NDS is gaining traction and in terms of penetration on the rigs, we are making progress there. So, we got to make sure we pushed the numbers, and that's what the mission is.
