I bought a SVEN PS-370 Speaker as a present for my son, today he tested it at the stadium, played basketball with the guys, and came home happy and in a positive mood. So the gift came to the right place. The user is satisfied - this is probably an indicator that the equipment did not fail? And I thought, I’ll ask him to sometimes give me to the sports ground. Now training will go more fun and an additional incentive will appear for training.
