Thank you, John. Good afternoon, everyone. Our financial results for the second quarter were the strongest in our company's history, as we made meaningful progress against each of our key financial objectives. This includes record sales of $172 million and significant improvement across our growth, operating and adjusted EBITDA margins. We also shift our highest number of pumps in a quarter reaching nearly 34,000 shipments worldwide. To put our performance and growth into context our pump shipments in Q2 were approximately the same as we shipped in all of 2018. This highlights the incredible progress we are making in expanding the market and taking market share at levels greater than years past. Worldwide sales were $313 million on a year-to-date basis, which is an increase of more than 50% over last year. As our installed base has grown nearly 270,000 customers, we see ongoing cartridge and infusion set purchases becoming a more meaningful part of our business. In addition, we are seeing a growing number of customers become eligible for insurance reimbursement following the expiration of their typical four-year warranty period, and as a result, we have an increasing number of repeat customers. Approximately half of our sales this year can be attributed to these reoccurring revenue streams, which enhances the predictability of our business. Our domestic business once again delivered strong growth in the second quarter with sales of $128 million, an increase of 43% over the prior year. This was primarily driven by more than 20,000 pump shipments. While the majority of our pump shipments continue to be largely made-up of customers who are new to Tandem, we once again experienced an increase in our customer renewal metrics. Out of the total number of customers whose warranties have expired to-date, the cumulative percentage of renewing customers is once again up this quarter. We are on track to reach a cumulative renewal rate of approximately 60% by the end of 2021, compared to 50% at the end of last year. Overall pumps shipments also benefited year-over-year from gaining full access to the United Healthcare Members, an opportunity that was not available to us until the third quarter of last year. Lastly, recurring supply sales to our installed base of more than 200,000 customers also contributed meaningfully to our year-over-year sales growth, increasing 44%. This brings our domestic sales on a year-to-date basis to $231 million representing 37% growth over the prior year. Turning to our international results, we demonstrated another standout performance in the international markets. We achieved record sales of $45 million in our international markets for the second quarter, as well as record pump shipments more than tripling to 13,200. On a year-to-date basis our international sales of $82 million were more than double the prior-year representing 26% of our worldwide sales versus only 19% in the first half of 2020. These results once again well exceeded our expectations in this highly unpredictable environment. The demand for t:slim X2 continues to gain momentum as awareness grows outside the U.S. particularly with the scaling launch of Control-IQ. The markets we serve outside the U.S. are about 2.5 times the size of the domestic Type 1 market with pump penetration averaging about half the U.S. rate. It's been challenging to predict the sales cadence internationally between scaling launches and COVID-19 restriction. But the overall progress we've seen in the first half of 2021 further strengthens our confidence that the international markets will continue to be a longer-term growth driver for Tandem. Taking into consideration our strong performance, both domestically and internationally in the second quarter we are increasing our 2021 worldwide sales guidance to a range of $670 million to $685 million, which is a growth rate of 34% to 37%. This includes international sales in the range of $160 million to $165 million nearly doubling our 2020 international results. We are confident that our technology will continue to expand the market and capture share even in this challenging environment. We continue to factor in some conservatism relating to COVID-19 as we've seen in the past few weeks, it remains highly unpredictable. Our guidance expectations also factor in the potential for competitive noise in the market. As we look to our anticipated cadence of sales for the rest of the year, summer seasonality is expected to be reflected in the third quarter, particularly in the international markets, then may also be more heightened in the U.S. this year, as we are seeing more prescribers and customers taking the opportunity to vacation post COVID lockdowns. Moving on to margins, gross margin meaningfully increased to 54% in the second quarter, up from 50% in the prior year and 52% in the first quarter. We drove this improvement through manufacturing cost reductions for both pump and cartridges from process efficiencies and increased production levels. Particularly as we continue to transition higher volumes to our third-party cartridge manufacturer, we also continue to generate cost savings and our other non-manufacturing costs overall, which primarily consists of warranty, customer training, freight royalty, and digital health support costs. From an average selling price or ASP perspective our domestic ASP for pumps remains strong, while the rapid increase in our international business has brought our global pump ASP down compared to the prior year. This is countered by a higher ASP on supplies for our growing international installed base, which brings positive contribution to our supplies gross margin. With a gross margin at 53% year-to-date we remain on pace to achieve a gross margin of approximately 55% for the full year. For adjusted EBITDA and operating margins, our sales growth far outpaced our increase in operating expenses, despite our ongoing investments in R&D initiative to support our near and long-term product pipeline, as well as our customer support infrastructure. Adjusted EBITDA which also excludes non-cash stock-based comp more than doubled to 14% and the second quarter from 6% in the prior year. We have now reached an adjusted EBITDA margin of 12% on a year-to-date basis. This leverage is largely attributable to the growth in our international business, where our network of distributors are responsible for much of the operating expense investment. Operating margin took an even bigger step up to 3% in the second quarter, compared to negative 11% in the prior year as our non-cash stock-based comp declined in absolute dollars and as a percent of sales. With the increase in our sales expectations, we are also narrowing our 2021 adjusted EBITDA expectations to approximately 15% of sales. In each of the last three years, we have achieved a positive operating margin and net income in the fourth quarter due to the highly seasonal nature of our business. Notably this is our first time reaching this milestone in a second quarter, and we expect this positive trend to continue for the remainder of the year. We ended the quarter with total cash and investments at $545 million, an increase of $32 million in the second quarter primarily due to strong cash flow generated from operations as well as proceeds from the employee stock plans. This brings us to a cumulative increase of $60 million for the year, even as we continue to fund key investment areas, including product development for hardware, software and digital health initiatives, strategic investments, and manufacturing scale up for t:sport. In summary, we have increased our 2021 worldwide sales expectations to a range of $670 million to $685 million, which includes international sales of $160 million to $165 million. Gross margin for the full-year is expected to be approximately 55%, and our adjusted EBITDA expectations are approximately 15% of sales. Our non-cash charges for stock compensation depreciation and amortization are unchanged at an expectation of approximately $80 million included as components of both cost of sales and operating expense. With that, I will turn it over to the operator for questions.
