[Dailydrool] bark collar

[Danielle L]

I can't find this in archives...so I'm posting here. While surfing ebay for fun dog collars, I came across a no bark collar that emits a high frequency sound that your dog can hear. I'm wondering if anyone uses this...and if any one has had success with this.  
 
Thanks!
