Love the system, but disappointed with the quality.
I live in Canada (Quebec)
My comment will be similar to Paul's comment.
I have been using the system for over 8 years before I had to replace anything. Almost everything was perfect, except the collar.
My dog learned extremely fast, and was happy to run around and play in my huge garden, while it gave me the peace of mind, knowing that he could stay outside for hours without getting lost in the woods (he loved chasing the deer), or running after the cars on the road, especially in the night because the dog is totally black: even a careful driver could have hit him.
The red collar that came with the receiver, was of poor quality, and after a few years, I installed the receiver on another more robust collar.
The initial guaranty was 3 years.
About one year ago, it still worked, but according to the seller who I had called for another problem, was not as good as the news one: he showed me the difference and I agreed.
So I bought the new "improved" one.
This time, the guaranty was only one year, but I did not care too much, because the first one had lasted so many years without problems.
But now the new receiver is really broken: seems that a contact moves inside, so it works on and off, depending on slight movements.
My dog ran away everyday in the past 4 days.
But - well calculated - it broke just a few days after the one year guaranty expired...
