This has been one of the best things Ive bought in a while and one of the biggest motivators. It measures both your PEF and FEV1 digitally. I use it several times a day as a game to try to beat my previous scores. It may seem silly to some but for me it is a great breathing exercise, bc lets face it, forcing air out of our lungs helps us cough and move that junk out. It also encourages me to do as much as I can do to get my numbers up!
