1 / 7Holercoco 3X Ultrasonic Rechargeable Anti-Barking Device
Holercoco’s 3X Ultrasonic Rechargeable Anti-Barking Device is a portable handheld trainer that uses ultrasonic sound alongside a verbal command. The listing claims a range of 50FT in one section and up to 65 feet in another, so treat the stated reach as inconsistent rather than a settled operating distance.

What to know before buying
- The listing says the device is not applicable in noisy surroundings, for hearing-impaired dogs, when more than one dog is together, or for dogs under 6 months or over 8 years. It suggests contacting the seller if training shows no improvement after two weeks.
Listing details to confirm
The listing gives inconsistent control ranges of 50FT and up to 65 feet, and battery claims of about 60 days and up to 180 days are not clearly distinguished by operating mode. It also calls the device rechargeable and USB-charged while listing “1 A batteries required. (included)”, so battery type and included power source are unclear. The claimed 3X coverage is not defined as a measurable range or area.
Who is it for?
A good fit for
- Owners seeking a portable ultrasonic cue to use alongside verbal commands and reward-based reinforcement.
- Buyers who can use it in quieter settings with a single dog within the applicable age range stated by the listing.
Less suited to
- Households needing a confirmed operating range or unambiguous battery specification before purchase.
- Training in noisy surroundings, with hearing-impaired dogs, with multiple dogs together, or for dogs under 6 months or over 8 years, based on the listing’s stated exclusions.

Aggregate ratings lean positive, with most ratings in the five-star category, while a smaller share falls in the two- and three-star categories. This suggests favourable overall reception in the available rating snapshot but does not explain individual experiences or establish how well the device works. Buyers should weigh that uncertainty alongside the listing’s unclear range and battery claims, particularly if predictable reach or charging behaviour matters for their training routine.
Frequently asked questions
How far away is the device claimed to work?
The listing is inconsistent: one section states 50FT and another claims up to 65 feet. Do not treat either figure as a confirmed operating range.
How is the device meant to be used?

Who should not use this device, according to the listing?
It states that it is not applicable in noisy surroundings, for hearing-impaired dogs, when more than one dog is together, or for dogs under 6 months or over 8 years.
What is included in the package?
The available package information does not provide an explicit box inventory. The listing mentions a wrist strap and an included battery, but its power details are unclear.
