I dont know of screenshots, but we feel the interface is worth it though now that Updox is available it is slightly less so.
With the interface, labs import directly into the charge. You get a message in your inbox, where you can then click on the labs, review them and sign off. The labs are imported as structured data so that you can acutually go into the labs and print off, say, all of a patient's hemoglobin a1c or all of his cholesterol results. Unfortunately, you cannot go into Reports and run a custom report based on a lab results, say all patients with HA1C over 7.0. Maybe they will add that in the future.
