Works as advertised. They're a bit longer (and therefore a bit bulky) but it was a good price. BE CAREFUL. The threads on one or two of my 5's weren't perfectly helical: so if you want to avoid accidentally snapping the rubber trying to unscrew them, don't fully tighten them if you feel some resistance. They're long enough that you can leave them screwed on as much as the friction from poor threading will allow, and they feel pretty tight. resistance on one of them.
