The Ailun Phone Tripod Mount Adapter works just as described. Form is simple and function is easy and self-explanatory. Works for landscape recording and upright recording. The only improvement I can think of would be to add a few white marks to line up a few different angles exactly, such as 90 and 45 degrees. I have seen other cell-phone tripod mount adapters that look the exact same as this brand. They may perform as well, but I have not utilized them, so I can't compare them. For the price, this is a great phone tripod mount adapter. Watch my video review of this phone tripod mount on Youtube by PsychOtto.
