Some examples of the most recent applications of the NRQCD factorization approach to quarkonium phenomenology are presented. In the first part of the talk the NLO calculations for \chicj and Υ decays rates are compared to the data and the results critically analyzed. In the second part, I show how information on the non-perturbative matrix elements can be extracted from the hadronic fixed-target experiments and eventually used to test their universality.
