Accurate delivery date, quality frames and lenses. Although it took 2 weeks to get, they were delivered on the date that they said when purchased.
Glasses and lens are great quality. Frames are comfortable and light. They feel slightly on the cheap side, but only time will tell on durability. For the price and lens quality, it's awesome. It's my first pair of blue light glasses, and I hardly notice a difference in everyday use, but my eyes do feel more relaxed while on a device.
