Hi Goodfella,
thanks for sharing your wisdom and offering guidance:)
Did you make your own template? I worry I am not getting the contours accurate enough or the fit tight enough... it always seems to finish a little lumpy. I have a fair bit of diffusely thinned hair on top so getting the guide marks particularly at the back is a little tricky.
And when it comes to shaving pre-attachment what technique do you use to avoid shaving too much?
