size genetics, x4 labs or andropenis

Hi, I have been using Andropenis for more than 3 months and the results are still not visible.
7 - 8 hour daily usage. per set is around 40 'to 1 hour. what should I do to get optimal results. while using this tool there are many inconveniences. do I have to change tools, if yes what should I use, size genetics, x4 labs or still andropenis.
my penis size:
flacid: 8 cm
erect: 11 cm
goal: 17 cm
