READ: This is a micro educator. I originally purchased a mini educator but my trainer swapped it out for a micro device. The remote for all educator collars is the same. Comes with so many extras like remote strap and magnet, multiple collars and tips. I went a different direction with my dog training many years ago. Barely used. Everything still works great! Pet training Up to 1/3 mile range Dogs 5 lbs & up Soft temperaments Expandable to 2 dogs Made in the USA The ME-300 Micro E-Collar is a low power unit with a 1/3 mile range that is specifically designed for small dog breeds over 5 pounds. With an identical “Mini” remote as its low to medium power ET-300 Mini counterpart, what sets this receiver collar apart is its 20% smaller and lighter, delivering 20% less stimulation. The small, stopwatch style handheld transmitter is ergonomically designed with buttons right at your fingertips, so you won't need to take your eyes off your dog while training. So if you're looking for an effective way to train your small breed pooch, look no further than Educator ME-300 Micro E-Collar. Of course, the ME-300 Micro just wouldn't be an Educator Collar without vibration and tone only modes, 100 levels of Blunt stimulation similar to a TENS machine, Lock & Set feature that allows you to save your settings in the remote, low battery indicators on both the receiver collar and transmitter, a two-hour quick charge time, waterproof design and a night tracking light.
