It's my first time buying prescribed glasses on Zenni. My item arrived faster than I thought. Because I also ordered another pair from WhereLight (just to try different shops). Comparing Zenni with the local optic store from my optometrist and WhereLight, the local optic store is way too expensive for me, and WhereLight's delivery time was longer (it took 7+ days longer). Quality wise, Zenni's glasses are very good in quality, I'm a happy customer, will likely shop at Zenni again next time!
