Does anyone use these? I've always shaved my legs but lately have been getting shaving rash even while using a completely new sharp razor. Not a big fan of getting waxed so it would either have to be suffering shaving rash, epilators or hair removal creams (or just let my leg hairs grow out and go au naturale

).
How much does it hurt?
Is there any particular brand/model I should look out for or avoid?
Do you get ingrown hairs?
Any tips or tricks?
TIA
