[EX Q]: 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 A]: positive

[EX Q]: The bands work great and I like the different colors which make the Fitbit more versatile. I wear my Fitbit all the time so I am able to change the band to coordinate with what I am wearing. Great price and made very well. I have had mine for about 2 months now and have had no problems. Received the item in a timely manner!!
[EX A]: positive

[EX Q]: Bad. Just bad. The fabric is scratchy and the seams are uncomfortable. And, the inner ball was the incorrect size. A waste of time! Sent it back the same day I received. It's too bad because it's a great idea, just a poor design and poor quality control.
[EX A]:
negative
