Silent analog watches and clocks not measuring any larger than 4" x 4", back supports, up to two pillows without cases, pens, pencils, erasers, paper clips, rulers, highlighters (for use on questions only), one book stand, one foot stool, one mouse pad, splints, inhalers, crutches, wheelchairs, casts, hearing aids, TENS units, eyeglasses, earplugs (must not be connected) or plastic material normally associated with the sport of swimming, medicine, feminine hygiene items and wallets.
Apparently a TENS unit is a device which produces electric impulses to help people suffering from arthritis. I had to google it. Also, if I'm next to someone who has a book stand, for pete's sake, I'm going to hope he fails. I don't even quite know what a book stand is since it's not like we bring in books with us.
