My contacts are moist and my eyes are happy at the end of the day!!! I was skeptical to try this because it was the "cheapo brand". I was using opti free which I thought was pretty good! I ran out and had a just in case bottle of the Equate sterile multipurpose solution! I used it and my soft contacts are softer than when using the expensive brand! My contacts are sliperier, moister and I cant feel my contacts. I wear monthlys, I have 7 days before I need to change them out and they feel like I just put a fresh pair in...... Thats pretty awesome. My eyes are not red at the end of the day and I am much more comfortable. So price comparison, opti free a little more than $9 for a big bottle, equate multi purpose about $3 for big bottle. Hmm you do the math. I hope this helps you at least try equate multipurpose and maybe you will be as pleasantly pleased as I am!!!!!
