غطاء بديل (Thrustbuster)

The replacement sleeve fits exactly like the original and the steps to swap it out are straightforward—the lock wheel clicks into place once you turn it past “ON.” I’ve already used it a few times and it’s holding up well, no slipping or loosening.

The lock wheel turns so smoothly toward the ON side that swapping sleeves takes no real effort, and the fit is snug enough that I don't worry about it slipping mid-use. The cap removal and re-lock sequence is honestly foolproof, even for someone who's clumsy with small parts like me.

The replacement sleeve fits exactly like the original, and the lock wheel turned smoothly to switch it out in under a minute. Thicker than I expected, which is a nice bonus for the price.
