Using the Quick Extender Pro for penile enlargement is easy to do and very effective. But how effective is it, really? There’s only one way to really know, and that’s to keep a journal of your progress. 
There are a number of different ways you can do this. Decide which one is right for you and stick with it. Otherwise, you may not know just how many inches the Quick Extender Pro has given you.
One way is to keep a spreadsheet or notebook with your measurements in it. Now, there are a few things you need to keep in mind when measuring. First, measure only when you’re fully erect. Measuring when you’re flaccid or only partially erect isn’t going to give you a good comparison. Second, make sure you use the same measuring device each time and that you measure in the same way. Usually, you measure from the very base of your penis, so be sure you always do. You want to be very consistent with your measuring so you know you’re seeing valid results.
You might also want to take photos of your erection so you can compare them later. Again, you want these photos to be consistent, so aim for the same lighting, same background, etc. You’ll want to also be sure you’re snapping the photo from the same angle, too. Make certain the measuring device or some other item for comparison is in the photo and can easily be seen. You may also want to take several photos from different angles because it may be difficult to tell how much you’ve changed from just one position.
That’s all you need to do to track your progress with the Quick Extender Pro. Just don’t measure too often—seeing tiny little improvements may make you lose confidence or momentum.
