Query: Best on the market!

This stuff, hands down, IS the best product on the market. You don't have to worry about getting eye infections, it REALLY gets your lenses clean, and hey, so what if you have to buy a separate cleaner. I can get 6 months usage out of one pair of disposable lenses when I use this product, along with the enzymatic cleaner. All those no rub solutions out there do nothing but promote eye infections. I'm getting over one right now after using one of them. It's no walk in the park either. And besides, what's better than peroxide to clean anything? Well, bleach and a bottle of Coke rank up there pretty high too but neither of those work with contacts. Anyway, highly highly recommend - I've used this product for 15 years and looked to switch because of the priciness of the product. Paid for that with two eye infections! Grab this stuff and a cleaner - you won't be disappointed!
