Fitbit Charge 3 / Fitbit Charge 4The easiest way to keep your Fitbit Charge 3 safe against chafes, dirt, dust, grime and everyday wear damage is by using an IQ Shield protector. Each protector is precisely designed for your Fitbit Charge 3 to make certain that all of the required openings are incorporated to keep your device fully operational. The high quality protective film also features a protective UV layer that prevents the protector from turning yellow, allowing it to remain crystal clear. Each protector is invisible to the naked eye and the smooth surface makes it give the impression as if no protector is installed. Each protector can be easily installed and removed just as easily without ever leaving any residue or marks that will damage your device. Included with every IQ Shield protector pack for the Fitbit Charge 3 is an installation squeegee, a microfiber cleansing cloth, a protector for your device, and a set of detailed instructions to assist you through your installation. All IQ Shield protectors are backed by a lifetime warranty that will replace your protector free of charge should it ever wear or need to be replaced.
