Review on Dyson DC24 Vacuum Brush Roll/Bar End Cap 🧹 by 4YourHome - Engineered for Optimal Performance and Durability by Teresa Miller

The internal retention mechanism (innermost cylinder) is taller/longer than the original part. This forces you to squeeze the cap on the end of the brush to close the cap. While it may not cause any side effects (I have just started using this item and cannot comment on its longevity), this item does not live up to the specifications of the original item.
