The product seems effective but it is difficult to use. It is very hard to squeeze the liquid from the container.

I have dry eyes and this stuff is the best. Always get it at a good price and ships out quickly! Very satisfied!

So much better on my dry eyes than the larger bottles that contain preservatives! Convenient for keeping in my purse or pocket too.

I choose these because they are individual single use drops. They are great for dropping in your purse/ pocket.

Little more than Systane ultra but like the convenience of single use packaging and no preservatives

This product is excellent for on-the-go eye lubrication! Highly recommend this product if you have dry eyes!

Was advised by my ophthalmologist to use these drops for my dry eye condition and I haven't had a problem since

Price was great and my wife uses these all the time. They help with her dry eyes during allergy season.

Best things for my dry eyes; it has no preservatives so I can use it as much I like. My eye surgeon told me to use it

This is a great eye product to buy in bulk to cut down on the unit cost. I wish Sam’s would also sell Refresh Celluvisc.
