Normally these are the best corn husk but this last batch I received was not acceptable. Corn husk were so small I can't use them. No return. Wasted money. Disappointed

Ex Output:
negative

Ex Input:
I was skeptical that this would work to keep my hound dog quiet - but it works like a charm! Maybe because her nose is more sensitive?? We don't always put her bark collar on, but when we let her out at night when her barking would be more disturbing to neighbors, it works as described. Sometimes we only put the collar on and not activate it - that also works now that she associated the spray with the collar.

Ex Output:
positive

I bought this headphone for my daughter. She loves it. It's super lightweight and no pressure felt either on head or ears after hours using. It also has awesome sound quality. Best value to buy for this price.

Ex Output:
positive
