Yeah, what I'm going to do, I'm going to break that up into two parts if you don't mind. One, I'll give you a couple of cases that were reported to us what gets the hospitals excited about what we're doing and then I'll give you a few other facts which I think are important. One, we had a report on a 52-year old male neovascular glaucoma, and had elevated risk for incisional surgeries. So, they used the MP3 probe. Preoperatively, he had a pressure of 32 and he was on four meds. Postoperatively, one week later, he had 19 IOP on two meds. Another case was a moderate glaucoma patient, female 80 years of age, preoperative pressures were 36 on three meds, postoperative, one week later, 12 no meds, postoperatively six months later, 12 no meds, and another one where we did the -- where we were doing the clinical studies, we now have longer-term data that one patient that was in advanced glaucoma preoperatively 28 millimetres pressure and four meds, one year later 10 millimetres of pressure, one med. Those are kind of things that get people really excited, and I think that starts to lead us into this point, which I'll give you in the next part, which is a little more color on the device. The first case was not on a commercial basis. It was not done until March 30 this year. Since then, we've delivered over 70 units. Six accounts have purchased more than one laser, 10 accounts have had their G6 for more than six months and of those, four of those accounts have already repurchased probes and those were at 60 units each. We've had six other accounts that have already repurchase probes in less than six months. We've had one account, use more than 240 probes. There's roughly 300 accounts that account for the top 20% of all accounts doing 50% of the cases. Of that, we've already sold 12 accounts in that. We've done more than 1,000 cases and I think, what it gets down to are a couple of very simple things. The doctors tell us it's titratable to the patient's condition in this era of personalized glaucoma therapy. It's non incisional. It's repeatable. It's minimal and there's no inflation or the eye is really quiet postoperatively, and the patient downtime or recovery time is significantly lower than anything else they've done. That's the part that gets us really excited, and I think we're really solving this problem as we've talked about in the past, which was let's get into this, what we call compliance war between the patient, not taking their meds on time and the physician trying to get them to take their meds. This is a real solution for that.
