I didnt have any luck with the male edge unit I actually broke 2 of them. Yes getting in and out is a snap and its easier to adjust but the surdiness of the
SG or x4 labs in my opinion makes it abetter device. I use the x4labs noose option and wear it for 1-1.5 hrs. I use the adjustment screws to increase the tension to a desired amount and in doing this it gives me about 1/2-3/4 of a inch adjustment which is more than enough. I find that about every 200-300 hrs I need to add a bar so the adjustment isnt a bigdeal to me.
