I got this not really knowing what to expect.
First, it's easy and it's not messy to use. You shave before using this each time (and in between if you want/need to), which is good - no waiting for 6 weeks of yeti legs like you have to when you get waxed. There is a moment of heat when you pull the trigger, then that's it. Areas where my skin is a tad darker, the heat sensation seems to be more intense, but totally bearable and I use it at full heat setting.
I have fair skin, dark leg hair, the perfect combi for this gadget.
My hair grew back less thickly than before after first use, then as I have used this as directed, each subsequent hair regrowth is more spartan, slower and fairer.
I have now done about 6 sessions and when I shave, I do not get the stubbly re-growth after 2 days nor the dark shadow of the hair lurking under the skin. My legs now feel smooth for about 6 days, then the fairer, finer hairs peep through and I shave / maybe use the gadget again. Shaving is also less painful. I used to sting when I shaved before starting treatment with this, probably due to the courser hair. Now I don't sting at all when I shave!!
It's not a quick fix, by any means, but it has definitely done the job. I enjoy the grooming element of using it. It feels like I'm pampering myself. Stick with it and I hope you get results like I have so far had.
By the way, the first cartridge has only just come to the end of its life, and that's after 6 treatments to: lower legs, underarms and lady garden ;-) Happy with the way 1000 pulses does 6 treatments.
