What to know before buying

Listing details to confirm

Power details conflict: the feature description claims a rechargeable 1800mAh battery and Type-C charging, while the product details say one included 9V battery is required. The title claims a 50FT range, but the feature details do not substantiate that figure. Treat the IP65 rating, 30-day use and about 2-hour charge as listing claims. The manufacturer says use is only for healthy dogs without hearing issues, and results may vary with the dog, surroundings, distance and placement.

Who is it for?

A good fit for

Dog owners seeking a fixed ultrasonic training aid for indoor and outdoor spaces.
Buyers who want multiple frequency modes and a dual-emitter design.

Less suited to

Owners of dogs with hearing issues, which the listing excludes from intended use.
Buyers who need a clearly confirmed power setup or a verified effective range.

The supplied evidence contains aggregate ratings but no customer-comment summary. The rating distribution is largely five-star with a small share of lower ratings, but it does not identify particular strengths, complaints or reasons. It cannot establish how well the three modes or claimed range perform in a buyer’s setting.

Frequently asked questions

Does the QueenMew FZK use a rechargeable battery?

The feature description claims an 1800mAh rechargeable battery and Type-C charging, but the product details say one included 9V battery is required. The listing does not resolve this discrepancy.

How many modes does it have?

The listing describes three modes: intermittent 25KHZ, continuous 25KHZ and variable 23~27KHZ.

Can it be used outdoors?

The feature description presents it for indoor and outdoor use and claims an IP65 weatherproof housing. Treat that rating as a listing claim, not an independently verified measurement.

Is the 50FT range confirmed?

The title claims 50FT, but the feature description does not confirm a range. The listing also says response may vary by dog, environment, distance and placement.
