As advertised, it cleaned my new glasses quite well without streaks or smudges. I give it 5 stars because I don't believe there are very many solutions out there that can clean like this. As for the smell some reviewers have griped about, it's not bad at all. Some people have overly sensitive nostrils, or are just paranoid or skeptical about everything. When you give your glasses to a clerk to be cleaned at an eye place, they return them to you, you put them on, and typically smell a kind of mild Windex-y smell. Koala is no different. I don't know what makes it smell like that (they all do), but I don't care, and here's why: 1) it cleans marvelously, and 2) if this stuff was ruining people's AR coatings, we'd have heard about it by now in the reviews. All it does for me is make things crystal clear with a a good cleaning. And my PC monitor too. Don't expect some miracle product. It still takes some effort to wipe both sides of each lens thoroughly to remove all smudges. (I smoke, which residualizes on my glasses & makes me have to rub a little harder & longer. If you don't smoke & don't work in a dirty environment, it will be easier for you.)

It cleans my glasses fine. However it has a really STRONG CHEMICAL SMELL that lingers, and I have to wash the chemical smell off my fingers/hands after I use the product. MY GLASSES ALSO SMELL FOR A WHILE AFTER USING THE PRODUCT. It makes me sneeze and my eyes (slightly) sting.

Believe the reviews! I have tried so many wipes, sprays, and cleaning cloths in the eternal struggle for clean lenses... including a number of other high rated items. Nothing, and I mean nothing, has ever truly worked to my satisfaction. Until now! BUY THIS KIT. One spray of the cleaner on each side of each lens and a simple swipe with the cloth and ZERO SMUDGES. Literally none. Even a good bath in the ultrasonic cleanse doesn't work this well for me. My order came in today and I'm already back to buy more. I want at least one of these magical cloths within reach everywhere I am and an eternal supply of the cleaner. I honestly don't know if the wizardry is the cloth, the cleaner, or the combination of the two. I just know that IT WORKS! Thank you, Koala Lifestyle!!!

I am very fussy about the cleaning fluid I allow to come in contact with my glasses and camera lenses. So after doing a lot of research and reading quite a few reviews on this product, I finally purchased it and gave it a try and can now report:

This product works as it claims. It removes fingerprints, dust, dirt, and spatter. And has even proven itself to be safe for cleaning my camera filters. It does not streak or leave any residue. I would definitely recommend this product and vendor.

My glasses get dirtier than a lot of other people's because I have horses. I use sawdust for bedding, which gets ALL over my lenses, brushing dirty horses basically transfers the dirt ALL over my lenses, and that's all on top of just regular daily stuff that likes to attach itself to my lenses.

This stuff works really well and the cloths are super cute. I even got bacon grease splattered on my lenses last night and was able to get it off using the Koala Kleaner. There were no streaks afterward.

I do get what some of the other comments are saying about the strong smell. But the smell dissipates really quickly. It doesn't bother me at all.
