I used an ET-300 to train my puppy, then replaced with this model so I could control both my dogs collars with one remote. Works flawlessly. Walking them both off leash is much less stressful.

I have years of experience using ecollars for training K9's. We purchased the 2 collar mini educator to reinforce nuisance barking and basic house manners for our house dogs. This system allows me to find the best sensitivity for each dog and lock the number in. This helps when more than one person is using the remote to correct a dog. The mini educator collars have been very effective training tools, and within a few days the dogs have a new respect for house rules with a clear, fair, and safe deterrent!

It took me a little bit to understand the directions to program the collars, but other than that they are great. It is nice to be able to correct either dog with just a touch of a button. I have not had any low battery issues, but I do try to plug them in once a week to charge.

Battery lasts for a couple days at a time. Excellent range. Neat vibrating function. Lights on the collars for taking walks or playing in the dark. I like the stopwatch style remote. Easy to operate. I like how the collars cannot accidentally be turned off due to the magnetic on off connector. I like how it has a find me feature which beeps if you ever lose the receiver from the dog. The only negative is that it's difficult to figure out the boosting mode without reading the instructions. But even that's not much of a problem.

It was a bit hard to understand the directions, but now that I have used it, it's fairly easy. The results of using the collar has been positive. My puppy has improved with the collar. He is more behaved, and doesn't jump at our plates during dinner, and has stopped chasing the chickens.

It took me a few days to really understand the manual and how to get it set up, but I usually struggle with technology. I was especially interested in getting it set right for my timid dog. He rarely needs any corrections, but if it is too strong for him, he freaks out for weeks. So I started with 10, out of 100. I am up to 25 and it seems to get exactly the results I am seeking. He listens, responds but is not scared. Perfect! My second dog is quite a bit more bull-headed; her number is 40, and it definitely gets her attention, but she is not afraid either. I love the lack of a warning beep, as that always frightened my timid guy. Now I correct either without alerting the other. Einstein was a bit pricier than I really wanted to go, but now I firmly believe it was worth every penny. You get what you pay for, and I got what I asked for in this setup. By the way, my timid corgi is 25 lbs, and the strong-willed pappy is 20 lbs. These are regular lap dogs that live a very good life. I would not hesitate to use this setup on even the smallest of pets, as it is designed to be extremely gentle.

One of our rescues came to us as a true yapper and quickly turned our other dog into one! We tried everything from positive reinforcement to negative....treats, crate, even the vibration collars. Nothing seemed to effect our Maltese. Barking seemed to be more important to her than anything...until we used our Mini Einstein training collars! After 1 week of training, they don't even wear the collars now. All I have to do is call their name and hold up the transmitter! Amazing! Now we can keep our dogs AND our sanity! Thanks!
