Does it come with instructions?

Yes it comes with instructions both with the product and again digitally by email.

does it improve my reaction time ?

We used these for my daughter to help her eyes work together. It was suggested by her vision therapist. I played around with it also and you do get better at focusing.

Are the balls removable?

You could fairly easily remove them by untying the knot at the end of the string. However it may be tricky to put them back on.

Can this be used in the bedroom?

Hi, Brock String is a vision performance training tool that can be used anywhere.
