Review on Alfzero Sunglass Eyeglass Necklace Retainer by Brian Alvarez

I love this eyewear holder for work. It's easy to use and keeps my glasses secure all day... Thanks to my knowledge gained in practice, I know the importance of always having my eyewear on during fieldwork in Industrial AND Scientific areas. The only downside is that its a bit bulky but it's a small tradeoff for the convenience it provides..
