Smart Film Starter Kit 6" x 6" Electrochromic Film Switchable Glass Eglass Pdlc

This is an excellent product and the seller is extremely helpful. You must watch sellers youtube video and pay careful attention to get this working. A couple other tips: copper tape with conductive adhesive works best (mine did not come with this), try to avoid using alcohol to clean the copper tape, and you can actually solder wire to the copper tape first before applying to film (avoids damaging the film with heat from solder iron).
