Review: Excellent bit of kit - Excellent bit of kit. I’ve already got the dogs trained to ‘loud’ acme whistle so it was easy transition to this ‘silent’ one. It’s just nice to have the option of a quieter whistle so I’m not bothering the neighbors when we are on our early morning walks.
Review: I was beyond delighted by the results - Worked wonders for my neighbourhood dogs. They were driving everyone insane with their constant barking, especially in the late evenings, and the owners were ignoring them. So I turned to this as a last desperate resort, not really expecting any miracles. I was beyond delighted by the results! Everytime they start barking I stand by the window and gave it a few blasts. it took a few weeks but the dogs learnt and they stop almost instantly when they hear it. They key is consistancy, you must use it every time you hear the barking and cover all the required frequencies for the different sized dogs. The higher frequences are truly silent and work brilliantly for the small dogs, the larger dogs tended to need the lower frequencies, which are audiable. Great range, easy to adjust, very effective. My one complaint is that the whistle cover tends to get stuck and needs some force to remove sometimes. Not really a major problem and it doesn't hinder the efficiency of the product, but it can be a slight annoyance.

## Features

- Whistle had Adjustable Frequency
- Protective end cap
- Quiet human audible sound to confirm whistle is working
- However the whistle is engineered to produce a relatively quiet whistle sound audible in the human range the sole purpose of this is to reassure the user that a sound in the required range is being produced
- The reason for this is that if the whistle is incorrectly set up when selecting the frequency then it will not function properly without this facility the user will not realise the whistle is not working
