Review on 👓 Goswot 144Hz Rechargeable DLP Active Shutter Eyewear compatible with Optoma, Acer, Vivitek, Dell, LG, and other DLP-Link Projectors - Boost Your Viewing Experience! by Scoony Taker

UPDATE, the seller contacted me and sent both replacements for the faulty ones, they work very well, no problems with syncing or keeping the charge like the replaced ones. Great CS. I bought 3 packs and got a pack of 2 boxes. one with a box with 2 units on it and a smaller box with pictures on it with 1 unit, 3 look the same, same charging connector position, same shape. but for two the sensor LED was aligned left to right and for 1 right to left. 2 identical ones didn't hold a charge like the others and one of them stopped working after 3 weeks,
