40mm Replacement Detachable Stainless Steel T Blade（02144 ）,Compatible with Wahl All in One Lithium Ion Trimmer 9864/9864SS/9686/9818A/9854L/9876L/9854 /WSS3L/SS2L etc. (Silver 3 Pack)

The Good: * These fit like the original * Very high-quality components * Backup for the inevitable failure (design flaw, of the original, not a flaw of the replacement) to keep an otherwise expensive set of clippers aliveThe Meh: * A decent price for 2x replacement blades ($22.99 at time of review) * They come oiled so they definitely need to be cleaned before useThe Bad:* Nothing.The Verdict:There is a plastic retainer piece for the spring that holds tension on the moving cutting blade which eventually breaks. This is a weak point in WAHL's overall design. When it breaks, and it will, you have to replace the trimmer for $80, somehow find a replacement plastic retainer piece, or purchase replacement heads like these.This is a pretty good deal on replacement heads, and is great that you get a backup for when it breaks again.Pretty good price to repair the trimmer since it still works just fine.Definitely recommend.

These replacement T blades from YAZIYIR fit the WAHL all in one trimmer perfectly. The blades are sharp and run smoothly and quietly. I can find no difference in performance or durability between these and the original blades. Overall, good performance and excellent value.

These fit well and without any alignment issues. They are sharp and cute clean without pulling hair or cutting into the skin.
