I have had ecollar for almost 2 years now. Started with the mini and was upgraded to the pro. I kind of like the mini better.
There are lots of features I love on this. It does what it says it will do.
My complaints are as follows:
1.)You can't really use the light function; it is not easy to do on the fly. I liked the ease of turning on the light with my mini educator, which I liked better than this model overall.
2.)It has randomly reprogrammed itself twice now. one of the times this happened after charging; I noticed that two buttons were not working... turns out it had put itself onto 2 dog mode and those buttons were for (nonexistent) dog 2.
3.)It does not float. We swim a lot. I keep it around my neck but I worry about losing it.
4.) There is no version for left handed people.
The good: I hear that it is better than other brands.
The customer service can't be beat. When my mini educator stopped working correctly, they replaced it and upgraded me to this model. They also replaced my collar and receiver when the receiver battery went out. First, they sent me the wrong battery, but instead of just sending me the correct battery, they sent me a new collar receiver; even better.
They are always friendly and helpful if you have an issue.
It seems to be a good company. I am happy with my purchase and overall happy with the product despite the couple of hiccups.
