Is Endermologie effective long term on lumps and bumps?

I  started endermologie just before Christmas, love it. Was a bit dubious at first, as I  didn't think anything would get rid of my bumps. I'm from Brisbane and its hard to hide your legs when its hot here so much of the time so I gave it a go, I'm up to my 8th session and really seeing results. I have been told to keep it up once a month after my initial 12 sessions to get the best results and still exercise, but def think its worth the money
