As you can see from the customer reviews, this little Educator ET-300 Mini has nothing less than 5-star reviews and for good reason. Everyday I recommend this training collar to companion pet owners because it is simply the best entry-level training collar for the price and can be used for about 90% of the circumstances customers describe for their desired training goals.

The design of this unit is excellent.  The receiver-collar is one of the smallest money can buy (2.0” x 1.5" x 1.1”, 2.4 ounces) and will work for dogs as small as 5lbs. Along with its vibration only mode (Tapping Sensation), it has 100 levels of static stimulation that gives the user a wide range of correction levels allowing you to turn it down so low that's its gentle enough for small dogs but has enough kick for larger dogs as well.

At first glance this new, rounded style remote looks a bit awkward, but nothing could be further from the truth. Its ergonomic, user-friendly, stop watch style design fits perfectly in your hand with its buttons right at your fingertips.

The manufacturer, E-Collar Technologies, does NOT include any training instruction with their e-collars, and neither do our competitors. When using an electronic collar its important to us that its used properly and responsibly. If you are not a professional e-collar trainer or familiar with the use of an electric dog collar this guide is an absolute MUST!

Today onlywe're offering a FREE, instantly downloadable copy of Byron's step-by-step, 40-page training guide included with your purchase. This invaluable, easy to use training eBook will walk you through the steps of properly introducing your dog to the electronic collar as well as using it for basic obedience training and an entire chapter dedicated to correcting behavioral issues.


The Educator Mini has many unique benefits that aren't available with other brands, however a couple of my favorites are:

Lock & Set Feature
After finding the lowest stimulation level that your dog responds to, this feature allows you to save the setting into the transmitter.

Booster Function
During high distraction situations, your dog may need a bit more stimulation to get his attention. This features allows you to preset a higher stimulation level (1 to 60) into the transmitter as well. With other brands you will constantly be fiddling with the stimulation levels and its easy to accedently over stimulate your dog especially in dangerous situations where you need to act quickly. With the Lock & Set and Booster features this is no longer a concern as everything is preset in advance and you never need to take your eye's off your dog to change settings.

C.O.S (Control Of Stimulation)
This advanced COS (Control Of Stimulation) used in all Educator collars gives the owner the ability to fine-tune the perfect stimulation of the training collar for most temperaments of dogs. This COS improves training results and provides a better training experience for the owner and dog alike.

Tapping Sensation (Vibration Only Mode)
The Educator Mini has 5 training modes. Using the Vibration followed by low-level Momentary Stimulation mode will quickly teach your dog to respond to vibration only in a very short period of time.

Night Tracking Light
Now you and other people/cars can clearly see your dog at night or in low light situation with the bright tracking light on the receiver-collar. The tracking light is controlled remotely by the transmitter and can be set to flash or stay lit continuously.

If you haven't noticed by now, I really love this compact little remote trainer and cannot say enough good things about it. Beside all the great features mentioned above, it's durable, reliable, completely waterproof (submersible), fully rechargeable (2-hour quick charge) LCD screen, 1/2 mile range and a great bang for your buck.

If you've done your research, I don't have to tell you that you wont find a higher quality, feature-rich dog training system on the market at this price!

Product review written by Byron Pappageorge
Senior product specialist and eCollar dog trainer since 2003.

If 1/2 mile is enough range and your dog isn't overly stubborn, the Educator 300TS Mini is the way to go!

If you need something with a bit more range check out the ET-400 (3/4 Mile).

If your dog is over 30lbs and has a stubborn streak, consider the ET-800 (1 Mile).

Because we give you more!

Beware of Unauthorized Resellers

It is important that you purchase from an “Authorized Dealer". Why? Because you will lose your warranty if you don’t. Be wary of prices out there that are lower than everyone else's. If it looks too good to be true, then it probably is! All the top manufactures enforce Minimum Advertised Pricing (MAP), which means if you see the same model on another site at a lower price, they are probably not an authorized dealer and/or a scam site.

It seems almost everyone these days is selling e-Collars. Over the years, we have seen them pop-up on myriad of different online stores from sites selling shoes to sites selling popcorn machines!

While many people do their research online,sometimes they feel more comfortable purchasing from a local pet store, but the best quality dog training collars at the lowest prices can only be purchased online. Most of the brick & mortar stores are huge chains that carry low end brands at a high end prices.

The large chain pet stores have a high return rate due to high employee turn-over. Typically, the big chains employ inexperienced workers who may mean well, but often give wrong advice and/or collar recommendations which lead to inappropriate purchases and perpetuate misunderstandings about remote trainers in general.

  Great training collar for small dogs

Sep 5, 2012

Reviewed By Chi mum
From Roxbury, NY


I searched for a long time to find a collar for my 6 lb chihuahua. The collars that target small breed dogs are not great. I read a lot of bad reviews about them, specifically poor range and short battery life. So I kept looking until I was advised to try this Mini Einstein collar by an employee at a pet store. Even though it will fit large dogs as well, its compact design makes it fit just fine around my little dogs neck. And he has a skinny little neck! All you have to do is cut the length of the strap to fit a smaller dog. And if your dog is larger or has a very furry neck, the kit also includes 2 longer metal contacts to ensure proper contact with the skin.

I am so happy that I took the advise and bought this collar. Definitely worth the extra money. The collar has rechargeable batteries that work great and charge up quickly. It's easy to put on / take off. And the range is very good. Even when my dog had run out of sight, the correction stimulation still reached him and he came running back. I also really like the "vibrate" choice rather than always having to use static shock correction. I rarely ever have to use the shock as he responds so well to just the vibration. And you can also really fine tune the amount of shock since there are 100 levels. That allows for finding just the right amount of correction. I also tested it on myself (around my neck) and although the static shock does smart a bit at level 20, nothing too painful.

Overall, I highly recommend this unit. Don't bother wasting your time with the cheaper collars, this one is well worth the investment.

  Amazing product, would buy again

Sep 27, 2013

Reviewed By Michelle
From Washington


I should have bought this a year ago for my 2 year old rat terrier. We've been through 2 training classes but we still have not mastered the "come" command. Since we do not have a fenced yard yet this collar allows us to spend more time outside playing ball and I don't have to worry about him chasing animals/people down the street. We mostly use the vibrate setting which he responds well to. The collar is still a bit bigger than I would like for my 13lb dog but it is smaller than most other collars. Also, after I received the collar and read the book I found out you can order even smaller prongs for very short haired dogs which makes for a better fit on small dogs.

  Freedom for my JRT and me.

Jan 28, 2013

Reviewed By Terry and Nikki the happy JRT
From Santa Rosa, CA


After numerous, frustrating obedience classes I was forced to take aggressive action to possibly save my Jack Russell Terriers life in an emergency situation. I live on a 400 acre ranch with coyotes, mountain lions and other predators. I needed 100% recall on my dog. The remote collar has been worth every penny. My JRT can now run, play and dig like a ranch dog should. She also "comes" like a bullet when I call her. She now really listens when I recall her. We wear the collar whenever we are outside, very easy and comfortable. I clip the transmitter to my jeans. So simple.
I love the light option so I can keep track of her at night when we do evening chores.
My JRT can now have freedom to be a ranch dog and I know I can keep her safe!

I was impressed with how my large German Sheppard responded to the this little collar. He doesn't go next door and chase my neighbors sheep anymore. He responds to the vibration most of the time now. Highly recommend this product.

  Battery lasts a long time

Sep 18, 2013

Reviewed By Lindsey
From Fifield, Wisconsin


So easy to use and adjust level of stimulation. If out in the woods, and away from distractions, my dog comes immediately. If around too many other dogs and temptations, the dog will often ignore the pulse, no matter how high it is.
However, he is a very large and muscular dog and you can see his leg lifting like he doesn't like the stimulation, but he is deciding to put up with it and not come if he really doesn't want to. The product works great, but he is still only 9 months and it looks like I will need to work with him more.
The battery lasts for over a week, I don't know just how long because I charge it once a week and have never run out of power.
