Snapped right onto my FLIP ZERO without any wobble, which was my main worry since these are replacements. The fit is identical to the originals, so swapping them in took about ten seconds.
Ordered these as spares since the originals get a lot of wear from regular use, and they click in exactly like the ones that came with the unit. The fit is snug with no wobble during the slide motion. Glad to have a backup set on hand now.
Lost one of the original slide arms during cleaning and figured I'd be stuck, but these snapped on and hold tension just like the day I unboxed it. Good to know they work as spares for the non-vibrating version too.
