I tested the Rabbit R3 for a month. Here is what works, and the one thing that does not.

*The Rabbit R3 is the first Rabbit I have not regretted carrying.* I wore it on my belt for thirty days, in three cities, across six categories of task. I am still not sure I would tell my mother to buy one. I would also not tell her not to.

What I tested, where: ordering food (Berlin, San Francisco, Toronto); booking transit (DB, BART, TTC); two-step kitchen-timer + grocery-list workflows at home; two-step "find a flight under $X and book it" workflows in airports; voice messaging through WhatsApp and iMessage; and a category I will call ambient note-taking — leaving the device on during meetings and asking it later to summarize.

What works

The hardware. The R3 is 92 grams (the R1 was 115 g; the R2 was 104 g). The push-to-talk button has the kind of click that you do not have to think about. The display is glanceable rather than immersive. The microphone array genuinely picks up speech in a noisy restaurant, which is a category the R1 and the Humane AI Pin both failed.

The Large Action Model — Rabbit's framing, not mine — has gotten better. The booking workflows complete on the first try about 70% of the time. The other 30%, the device tells you why and offers to hand off to your phone. That hand-off used to be a failure. The R3 makes it the second-best path, which is genuinely the right product call.

The one thing that does not

Battery. Real-world heavy use: 4 hours, 40 minutes. Marketing claim: "all-day." That is not all-day. I returned to a charger by 2 p.m. on every weekday I tested. The R3 charges fast — 0 to 80% in 28 minutes — but the cable is proprietary, which is a choice that does not have a 2026 justification.

The first Rabbit I have not regretted carrying. Also the first Rabbit whose proprietary charge cable I have lost.

Pricing: $329, including six months of the Pro tier. Comparable: nothing, exactly, and that is the strongest thing about the product. Apologies in advance to the team if this gets fixed in the September firmware. As of today, the verdict is: buy it if you have wanted a wearable AI device and have not bought one. Skip if you have an R2 — the upgrade is real but not $329 real.
