It is the right size to hold in hand and keep in pocket.

It’s the perfect size and fits right in your pocket with ease

It is a good size to fit in your hand and the wrist strap is great

My husband and I bought these to take along on bike rides with us and they are the perfect size.

Worth the money and will recommend to others in the future.

Totally worth the money if you have a lovable but naughty pup!

Not only does it deter bad behavior but it is a great training tool

It’s been a great training tool for us, especially when not overused and not meant to cause pain.

As long as this product is used consistently, this could be a great tool!

Seems like a great training tool and I'm excited to try it out

It’s a great training tool for a dog on a leash that likes to bark at every person and animal they see

It’s still great, good value for money, afraid of static electricity, and never tried electricity

The dog ready repellant tool is a great value in its use as a dog training tool, bark reducer in the house, and for reinforcing potty training behavior.

This one had a good price (though not the cheapest) and had great ratings.

It’s a great price and the dogs respond to it very quickly

Greedy price

This was a good price and it actually works for my puggle

When I saw this product on a flash deal I thought it was a great price and was willing to try to see if this was possibly the answer.

This supersonic device did distract my dog the first few times we used it, but she quickly became accustomed to it and started ignoring it completely after about two days

Easy to use various methods make this a great training device with easy reinforcement.

This little device is so handy for getting your dogs attention

This device was so easy to use and has made such a quiet difference in our home

It seems like a good little device that can be concealed from my dogs and it has gotten their attention when I use it

Very glad we bought this humane and effective training tool

It’s a great training tool for a dog on a leash that likes to bark at every person and animal they see

n’t feel like this has ever harmed her, but only makes her pay attention to me

Our dogs are more stubborn than most, and may need more stringent training approaches.

Seems like a great training tool and I'm excited to try it out

I definitely recommend purchasing the Ultrasonic Dog Repeller device

Great purchase, it's worth a shot if you're looking to get serious about breaking bad habits or training your fur babies.

This was a great purchase and use it on a daily basis with NO harm to my dog

A vibrating collar (NOT shock) works 100 times better to get her to stop barking

It’s been a real issue since I’ve been working at home because they interrupt meetings when they see other people walking on the street or if any packages or delivered by barking loudly

I was skeptical, but this works and it’s not expensive.

You have to create association while pressing on the bottom, for example, push on the bottom and after tell "do not do this" working perfectly, like mute button on TV remote :))but 20$ coupon fake

The rechargeable frequency emitter does amazing work on our 4m old puppy!

We use just the loud beeping button and he will immediately be more gentle and calm

Works well but sometimes have to switch to audible beep.

A few beeps seems to break the barking pattern most of the time

Now they see me pick it up and I press the audible beep and most

I give her short audible beep then high frequency sound

While out on a delivery, within the first hour of being on my rout I was being charged by the homeowner's dog, this thing confused it enough to give it pause and reconsider its actions

and wow this thing is the only thing that’s ever worked on them

The best thing I can say is that the barking deterrent worked so well that I seldom have to use it.

I tried everything from shock collars to the stupid tree house things

One thing I really do like about this one as opposed to the competitors is that it is nice and small and much easier to carry around or put in your pocket when you are out on walks.

I like the extra’s that came with it!

If you have a stubborn dog like me give this device a try

Has not only stopped my dogs from barking but ran off a strange dog who was threatening mine

They kept barking but my dog walked like a champ and even ignored the other dogs

then I encourage you to give this Dog Barking Deterrent a try

Easy and simple to use, my dog immediately stops barking after pressing it

Beep works as reminder and ultrasonic stops dog barking.

We have tried many things to deter the barking and had no success

I have only pressed the ultrasonic button once, that was enough to deter her barking.

This product works for short range irritating barking from dogs.

Really liked the product it was easy to use and stopped our puppy's annoying barking.

I used this device as instructed (pressed the tone button then the ultrasonic sound button immediately after) & my dog stopped her bad behavior instantly.

Was completely surprised by how effective it is in stopping unwanted behavior in my dog

I continue to use it with my own dogs to curb unwanted behavior quickly

I'm using the beep button for a different positive training behavior

Her behavior is improved, but we have to still hit the button for the beep that we both can here

so I don't have to use hurt their ears once they catch on.

The sound does not seem to upset him or hurt his ears, instead it grabs his attention super quick and gets him to calm down before he even has a chance to get riled up

Only weird thing is my son can also hear the sound too and says it hurts his ears

If you do get this supersonic device, don’t be like my fiancé and point it at the dog with another human between the device and the dog, it hurts your ears if you’re directly in its path.

n’t like, but this doesn’t appear to hurt his ears, but is strong enough to get his attention and stop his barking.

I'm not a dog trainer, but this has given me hope that I can retrain their undesirable habits

Great purchase, it's worth a shot if you're looking to get serious about breaking bad habits or training your fur babies.

n’t feel like this has ever harmed her, but only makes her pay attention to me

Anyways, my fiancé and I purchased this device to help break some bad habits Loki has

n’t feel like this has ever harmed her, but only makes her pay attention to me
