I was a little concerned about trying this as I’d heard that these ‘safety razors’ were actually more likely to nick your skin. However, after watching a how-to video on it I’ve had no issues apart from a paper-cut (that was user error!). The trick is to let the weight of the handle do the work and not put any pressure on your skin.
Gives a really close shave and easy to rinse clean afterwards by loosening the head of the razor a bit. Really happy to have found a decent plastic replacement.
