I personally loved the item initially, but the quality did not uphold well. The vibration option was typically enough to get my pits attention and the LED came in handy during nightly bathroom breaks. After (quite easily) snapping one of the arms to the electronic device while stretching the collar a couple weeks later, I couldn't get in contact with the manufacturer and the company that issued my coverage said it didn't cover accidental. Might do well for smaller dogs. Started great, ended up disappointed.
