Review (5/5): Great set of replacement blades!
The blade on my cheaper set of wahl clippers became dull ( the precision marked ones), so I decided to replace them with the ones found on the wahl seniors. Comes with oil, screws and two well lubed blades (stationary blade, and moving blade). I did however used my older screws because the ones that came with theses weren't wide enough.
These blades love to grab a hold of hair, and cut it off. I noticed the difference in the cut quite easily. I actually think they are a lot better then the one on my oster fastfeeds.
Comparing my fastfeeds ($50) set of clippers to a wahl $20 with a $10 blade on, i actually like the wahl combo a lot more. The magnetic motors in the cheap clippers move the blade very fast, paired with a sharp blade you get a clean cut. A good way to improve the potential of a cheap pair of clippers.
