I'll buy this again! [SEP] I have some Oster clippers that are at least 20 years old. I was considering replacing because out seemed noisy and even though I had my blades sharpened, I wasn't always getting great results. But I was spending a lot on additional grooming equipment so decided to try this blade with some combs that happen to fit a size 30. What a difference! I'll probably buy another one of these blades just so I have an extra. I think my Oster clipper runs like new!
