After months of use, I can say that it is a product of very good quality, cheap, fast delivery, the strength of this product lies in its scalability, indeed it offers multitude of solutions in terms of weight: 5k, 10k and 15kilos to a good start, what is more it is quiet, no noise when performing his daily exercises as is the case with steel ones, and I do not have that Chronic afraid to tell me when was the goupies that block the barbell plates will they let go?
