After installation, however, you realize that everything lacks stability. Impossible to tighten the nuts, which creates the game This gives the impression that the media can easily fall if we're not vigilant when raises the dumbbells above.
I do not know if this problem is defective parts in my order, or if this lack of stability is "normal".
In any case for the moment, I remain very cautious when using this media. Personally, I find it a bit unpleasant; but I'll see if I'm getting to use.
EDIT: after a few days of use, I finally adapted very well to this lack of stability, yet a little scary at first. The value for money is actually very good as indicated another comment.
After that, it is sure that if you search for the very good quality, there is probably more stable or more "pro" products but more expensive. Personally I rather works with endurance not too high loads (40 to 55 kg) for the squat and the bench press. This product suits me very well for that use. However, for the work with much heavier loads, I do not know if this product is suitable.
