Incomplete instructions
I have used the product only once since receiving it, so I am not yet able to rate it. However, I believe the instructions should be more complete; I.e., had no idea that I should use separate eyecups for each eye, no instructions to shake well before use, use distilled water, and why distilled water anyway? Found the answers on amazon website by mostly others. Couldn’t this information be included with product?
