+                      <p><strong>UPDATE</strong></p>
+
+                      <p>I've never thought that creating a PCB was so easy ! (let's undertand ourselves, right now I'm talking about the CNC part, when you've already have a design ! Thanks again Adrian and Quentin ^^)</p>
+
+                      <p>It's astounishing how the CNC can be so precise. At first I was a bit afraid to rub the toothbrush on it while cleaning because I thought the lines would come off but they didn't !</p>
+
+                      <p>And even though Mods is a real mystery, especially weird when you open it and there's nearly nothing on the screen, it really is effective and not so hard to use when you know it a bit.</p>
+
+                      <p>But I'd still be amazed of the people who created it ! There must be such a work behind it.</p>
