Started grooming when there were only Oster blades. It seems that after all theses years and now so many brands, the quality of the blades has declined. It’s to a point that I am afraid to purchase an unfamiliar brand with the possibility of just wasting my money again. Groomsaber caught my attention with the changeable back blade so I decided to give it a try. After a month using the Groomsaber blade I am very happy and have not had the need to change the back blade yet. I will be a returning client.
