195 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other dog and cat food, health, gear and grooming we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
['The ET-300 is built by E-Collar Technologies specifically for small to medium dogs, with the kit including a charger, the collar and receiver, contact points, a lanyard, and a remote with a finger clicker. The collar strap is made of biothane, a rubber coated material that wipes clean and holds up well outdoors.', 'It offers 100 stimulation levels along with vibration, tone, and light modes, described by the manufacturer as humane tapping stimulation rather than a single fixed shock. That range of levels gives owners much finer control than a basic collar with just a few modes. The remote reaches up to half a mile, more than enough for most training sessions.', "At $199.99 it costs more than the budget collars in this category, but it's backed by E-Collar Technologies' 2 year warranty on the transmitter and receiver and a 1 year warranty on accessories. A 4.4 star average across 195 reviews reflects a smaller but well regarded customer base."]

Performance notes
With 100 stimulation levels available, owners can start at a very low setting and adjust in small steps rather than jumping between a few coarse modes. The included finger clicker on the remote lets you pair a stimulation with a clicker cue in the same motion, and the biothane strap is built to handle repeated outdoor use.
What buyers say
A 4.4 star average across 195 reviews is one of the higher ratings in this category, though the review count is smaller than some higher volume budget collars, suggesting a more specialized customer base.
It's designed for a single small to medium dog. E-Collar Technologies makes other Mini Educator models sized for larger dogs if needed.
What does 'tapping stimulation' mean?
It's the manufacturer's term for the collar's correction feel, described as a humane tapping sensation rather than a single harsh shock, adjustable across 100 levels.
What's included in the box?
