rurun_buddy_42 VerifiedDay one review: I'm suspicious but impressedJune 29, 2026
I've had these twelve hours. Unpacked them for my long run recovery routine. First impressions: they pack flat inside my duffel bag, no bulge, even with the 8-inch pair. Light enough that I'm worried they're cheap foam, but they're not—they're solid. I pressed my thumb into the surface and it barely gave. We'll see if they delaminate after a month of hotel floors, but so far? Suspiciously good. The texture is smooth but not slick. I'd bet money these survive a cross-country trip.
- titired_mom_4am VerifiedBattery lasts forever, and my baby finally sleeps
June 27, 2026
I ordered these for my restless leg syndrome, but I think they're actually white noise machines? Or maybe it's the teething toy? I don't know, I haven't slept in 48 hours. The 6-inch disc vibrates when you tap it against the crib, and my baby calms right down. Also, the battery hasn't died yet—I've used it for three nights straight. Wait, do these have batteries? I'm too tired to check. Anyway, my toddler chewed on the edge and it's fine. Definitely recommend for colic.
- bobob_berner VerifiedEdited review: missing part was in my dog's mouth
June 18, 2026
Original: The 6-inch pair came with one disc that had a chunk missing from the edge. Unusable. Contacted Nimbus—no reply yet. Edit: Found it. My dog chewed off a small rubber nub and was hiding it under the couch. So it's not a defect. After reassembling, the disc is fine. The stitching? No stitching here, it's molded rubber, and the seam is invisible. Held up fine. Sorry for the false alarm. Still, maybe don't leave them where dogs can get them.
