Choosing running watches & heart-rate gear is really about matching the heart-rate accessory to your training setup. Do you need Bluetooth and ANT+ in one chest-worn monitor, or is wireless ANT+ enough if a used strap package suits your needs? ROCKBROS and Garmin HRM1G answer those questions differently, with the first emphasizing rechargeable, water-resistant hardware and the second focusing on a wireless ANT+ chest strap. Connection type, charging, condition, and price are the practical tie-breakers.
Quick verdict
ROCKBROS fits a rechargeable, multi-connection setup, while Garmin HRM1G fits a wireless ANT+ setup when used condition is acceptable. Choose ROCKBROS for the combination of Bluetooth 4.0, ANT+, magnetic charging, and IP67. Choose Garmin when the stated wireless ANT+ format and a lower upfront price matter more than having a battery included.

Where each product wins
ROCKBROS wins for connection flexibility and water exposure
ROCKBROS has the broader stated connection mix, naming both Bluetooth 4.0 and ANT+. Its title also specifically covers cycling and running, while the description gives an IP67 waterproof rating. That combination makes it the more fitting choice for a runner who wants one heart-rate monitor to serve more than one kind of connected workout and who prioritizes water resistance.
Garmin wins for a simpler ANT+ package
Garmin HRM1G is the clearer fit when wireless ANT+ is the connection your setup uses and a black fabric-harness chest strap matches your needs. The $8.89 difference between the two listed prices also gives Garmin the upfront-price edge. The trade-off is that the unit is used and the purchase does not include batteries or other accessories unless shown.
Product notes
ROCKBROS Heart Rate Monitor
ROCKBROS earns consideration for runners who want a rechargeable sensor with two stated wireless modes. Bluetooth 4.0 and ANT+ give the setup more connection paths than a title that names ANT+ alone, while magnetic charging and a 70mAh lithium battery make the power design clear. The waterproof wording and IP67 rating are another concrete reason to choose it for sessions where water exposure is part of the plan. The limitation is its format: the listed attachment is a torso chest strap, so it is heart-rate gear rather than a watch-format device. Anyone specifically shopping for on-wrist running functions should not treat this monitor as a substitute for a watch.
Garmin HRM1G Wireless ANT+ Heart Rate Monitor
Garmin HRM1G makes sense for a runner whose setup uses wireless ANT+ and who wants a black fabric-harness chest strap. The purchase includes one chest strap with the fabric harness, giving a concrete reason to choose it when that wearable format is what you need. Its limitation is the used condition: scuffs and other signs of use are explicitly part of the description. No batteries or other accessories are included unless shown, and the title says "No Battery," so the package is not the right pick for someone expecting a battery to come with it. The trade-off is straightforward: Garmin offers a narrower stated connection description than ROCKBROS, but its purchase centers on the strap itself.
Final choice by use case
- Choose ROCKBROS if both Bluetooth and ANT+ matter, or if the IP67 waterproof rating is central to your running or cycling routine.
- Choose Garmin HRM1G if wireless ANT+ is sufficient, a used black fabric-harness strap fits the plan, and the lower listed price is the deciding factor.
- For the price-sensitive choice: Garmin HRM1G is USD 25.95 versus USD 34.84 for ROCKBROS, an absolute difference of $8.89.
For most feature-led setups, ROCKBROS is the more flexible match. Garmin HRM1G is the focused alternative for ANT+ users who can accept a used, no-battery package.
