Very beautiful necklace which was not the time to enjoy

By cons I put it 3 stars because of something that looked pretty good to buy and which proved to be a hell.
The safety opening (so your cat does not choke if he stuck his collar somewhere) can be set on 3 levels, related to the weight of your cat.
When I received my necklace, I determined on its first level, which is the weight of my cat.
Very quickly he managed to get rid of it (with all that had been added to his collar: medal, flash code, a light and another bell).

I bought exactly the same necklace and accessories that he had, as before (it's cheap).
This time I set the safety on the second level (ie more than its weight, normally). It took him two days to get rid of it and I'm looking in the area, could not find it ...
He still had not even received his new medal she happens next week ...

Since it is very reckless, I can not leave without a collar so I have to buy a third with all accessories AGAIN. It's getting very expensive.

I think this time, although I find this beautiful necklace, I will turn to another brand !!!!
