This Review Title is I'll buy this again! and the content is: 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!.There are other information for this review, one is This reviewer did purchase it and the other is 7 people think this review is helpful.
