In general, I am satisfied with the column. If it lasts for three years, respect to the manufacturer. Pros below: Ease of management. The sound is big enough for an apartment. In the open air, the sound perception radius is 10 m in diameter. It does not wheeze at maximum volume. Good bass. Cons below: After the last shutdown, it does not remember the volume level and playback mode. Loses bluetooth connection beyond 5 m.
