This review is from: Mammoth XT Ultrasonic & Supersonic Dog Training Whistle with Keyring (Misc.)
When I first used this whistle I was quite pleased with it but very soon the two pieces came apart, the adjustment of pitch is just by unscrewing them until the dog responds the best to the sound. The first couple of times I actually found the missing part - it even came unscrewed whilst in my pocket - and I was intending to glue the two parts together but totally lost the bit before I could. If you buy this then make sure you adjust it then stick the 2 parts together - or just don't buy it.
