Promising review: “I bought this nifty gadget about six months ago for a multi-leg, ultra-long-haul trip and it more than held up the entire duration. I was able to finagle it to fit the tray tables on different planes, and like others, I find the height just nice when clamped onto a stowed tray table. It also works on my roller carry-on handle during layovers. However, I find myself using it a lot outside of travel, too! Work-wise, I’ve clamped it onto my office desk shelving to hold my phone at eye level beside my computer. At home, I simply clamped it to a deck of cards, and it turned into a versatile stand that I could place on any flat surface. Heck, I’ve been using it to hold my phone comfortably at eye level while watching videos in bed. It’s extremely well-built, and I find myself fidgeting with it all the time. Thus far, it still feels solid, and I don’t anticipate breaking it any time soon. Even if it does break, I’ll be happy to buy another one or two of it!” —Earendil
