Customers find the whistle offers good value for money and appreciate its variable volume control. The functionality, noise level, durability, and build quality receive mixed feedback - while some find it very functional and loud, others report it stops working, doesn't last long, and feels cheaply made. The battery life and button accessibility also get mixed reviews, with one customer noting the batteries last longer than expected, while another mentions the button is not obvious.
