Not the end of the world we took his collar holding the whistle off at night anyway, however the more frequent trips to the charger weakened the mount and now the whistle is lost somewhere in the yard

Plastic mounting bracket cracked and broken after a few months of use.

However, the mount doesn't appear sturdy enough to keep from breaking if the unit gets snagged on something

The mounts keep breaking, the batteries don't last longer then a few days on a single charge (supposed to last over a week), and the nubs on both monitors have worn down so much that they don't clip into the mount anymore

The mount on the dog collar which holds the whistle is shoddy

People who need the latest toy, however limited its use?The single best use for this is as a reminder for meds etc, but then your calendar/phone/spouse/alarm can also do that, without hanging a relatively large chunk o' metal around Fido's neck
