I have had this product for well over a month, and it still works great, so just be aware that the other reviewers might have had faulty products and just needed a return. Maybe their dogs are a little crazy and rough house the collar a bit too much. It is a relatively durable case, but I believe that strong impacts would do some damage to the unit. Some good and bad points now:
- The spray is VERY effective for curbing barking
- Is not sensitive enough for small barks and whining, so this does not solve those problems. If your dog is smart and figures out that quiet barking is not punished (like mine did), you'll still have a problem barker, but just not as loud.
- My dog is not afraid of the collar, but knows to be quiet when it is on
- Make sure you say 'no barking' or 'quiet' every time it sprays if you can. The dog will learn your command as well.
Overall I highly recommend this product for $40. However I do NOT recommend it if you bought it at the $100 that Petsmart wants to steal out of you (though I do love that company). It is simply not a $100 value anti-bark system, more like $40-$50.
