I was worried a spare wouldn't feel the same, but this one keeps that snug sensation just right. Swapping it in took seconds and now I don't have to toss the whole thing when the old sleeve wears out.
The snug fit is exactly like the original sleeve, no loosening after a few weeks of use. Swapping it in took seconds since it sits the same way. Honestly it's saved me from buying a whole new unit.
Wasn't sure a spare would feel the same, but the snug fit is identical to the original sleeve that came with my device. Cleaning is quick and it holds up fine after several uses.
