I bought this instead of the real Muro 128. We have the generic Muro 128 gel and thought that a generic eye drop wouldn't matter. At least with this product, getting a generic did matter. It created a burning sensation in my husband's eye. I think whatever residue is left behind (what the one reviewer mentioned) was the culprit. Every brand has different inactive ingredients I guess and whatever inactive ingredient is in this one didn't work well for my husband.
