I am very pleased with this Refresh product. Had been using another eye lubricant product for years, and then recently the product was removed entirely from the marketplace. Seems people had numerous issues with this product, but I didn't. So, did my research to find a similar eye lubricant product and read the reviews for Refresh and thought it was worth trying. I now love the fact that it comes in individual, daily containers that can be easily thrown out. Great for travelling. The product immediately soothed and lubricated my eyes for the entire day. This particular eye drop is somehow thicker in formula than my previous one and maybe that is why is can last the entire day. I use my laptop for hours during the day and I find that my eyes are not as tired, or that I am rubbing them as much. Don't forget, these hot summer days are very hard on our eyes; what with the sun, the wind, the dust, the pollen and even the A/C can dry our eyes out. Would gladly recommend Refresh.
