This is an excellent kit and what is considered "the standard" in fit testing for respirator users. You have to be somewhat experienced to use this kit or a very good follower of directions. The kit works perfectly out of the box and new things are always more fun than used things. Be sure to take the paper off the faceprotector! It is there to keep it clean while shipping but needs to be removed to do the testing!
