Both of my machines have them now. Upon receipt, CAREFULLY remove the protective film from both sides of both visor shields. DO NOT scratch the lenses, be careful and wear gloves to avoid damaging the plastic screens. I ordered my first set and found a very small internal defect in materials that was not visible until the smoky protective film was removed. After notification, 2 new packs were sent (although only one pack was defective). Upon receiving the replacement I labeled both the damaged and undamaged items and following the instructions I was able to return the first set free of charge via my local UPS shop. Both the product and the service were exceptional. Yes, these screens work. You can see right through them when driving in the sun. It's still very bright, but you're not blind and can't see the cars in front of you. The night glare protection does what it promises: it blocks out the glare of oncoming vehicles' headlights, so you can see and drive more safely. Considering you can get two packs for just over $20 and they're advertised on TV for around $19.95 each, these two packs are a steal. If you only have one car, carry a driver and passenger visor, or gift one to someone you want to drive more safely. UPDATE - Just got back from a trip where I drove straight into the setting sun. Sun visor lowered, sun visor adjusted slightly to get the perfect vertical and horizontal position and everything worked like clockwork. As the sun went down the sun visor pivoted up (I hold one forward to the windshield and the other back to the driver, not only did it sharpen the fading sunlight but it also started catching oncoming high beams. Also note that some people Had adjustment and fixing problem, you need to make sure that the adjustable part of the holding frame is fully pushed in, which requires caution, because the inserted part tends to have a little bending problem.Some finished thick (thick) factors with sun visors is suitable, but with a little pre-compression of the sun visors with some vise this problem is easily solved i was a little skeptical but for the price mentioned why not i was pleasantly surprised and now that i use them in the real world i recommend it to everyone
