As a new contact lense wearer I have struggled to the point of not wanting to wear contacts at all with the problems of them being inserted correctly (inside out or right side). After receiving this product I no longer have any problems at all in inserting the contacts. I must order another one, just in case something bad happens to the one I have as I just couldn't be without.
