Customer’s self-reported numbers of penis enlargement results!
Our customers are offered a private online diary, where they can log the number of hours using the product, the traction level and of course the occasional measurement of length. We got access to the ones permitting this (349) and below are the results. We divided them into 3 groups according to their starting length (blue, orange, and green), and we added the results of our own survey (purple).
Interestingly the men who started out with the shortest penises, gained length seemingly quicker (blue) than the men who already had average or above average length. Also we saw that our claims from our own testing are the correct average numbers.
Self-reported numbers are very credible for science purposes, since the men are not motivated to either add or subtract from the truth.
