Hmmm, Easy to use, no buffing or sanding and showroom bright in 30 seconds. Uh, not exactly. It was easy to use, two separate containers; one of polish, one of protectant and a scrub pad/polisher all in one are included. It took longer than 30 seconds to clear the oxidation and crud from the lenses, even after a good scrubdown with soap and water first! With about a half an hour and a good buffer, it might look showroom bright. But I call total BS on no buffing. I was going in circles with the polishing pad for about 25-30 minutes per lens. Did it work? Well, yes, the lenses are clearer and more light shines through. Showroom bright? No, but certainly better than they were before and more light is definitely coming through the lenses now.
Would I recommend it to someone who doesn't have a good grip with their hands anymore? No, there is a lot more scrubbing and buffing than they advertisement shows. And one thing that the direction wasn't clear on was whether to wet down the pad before applying the polish or not. Having used polishing compounds before, I wet down the pad first. But you can compare the before and after shots to get an idea.
Bottom line, it was worth it for me to get better light from my headlamps so while it wasn't exactly as advertised, it did work.
