I already draw some freehand sketchs with it. This item has been tested and I completely agree its of good quality. So glad I bought more, theyre beyone comfortable. Ive reached speeds of 30 to 40 mph and never once worry about loosing my phone. *Note: I work in a call center. I usually just leave it plugged in tho so I dont have to worry about it dying. If you use these, remember to turn off any "equalizer" on your phone or device. It breaks by either the person I am talking to cant hear me. It appeared sturdy and strong, efficient because I could mount it on the 4x4 post in my garage. My three star review is based solely (pun intended) on the fact that they are the LOUDEST flip-flops I have ever owned.
