Question: Bought this seven months ago and use it only occasionally when traveling. Bad surprise, it just stopped working without any warning. Tried it on another surface, same result. It's a shame since the design is great and it would work overseas.

Answer: 1

Question: Looks good, easy, easy to assemble. Instructions and parts w/ Hex wrench included were shockingly easy to use and assemble. Overall solid parts, arms a little flimsy. Quality overall is very good. Head rest may prove to short even when adjust to it's highest position for people with broad shoulders and 'normal' torso length. Arms not very sturdy, not adjustable (I missed this in the description--my issue). Overall, for the price, will work for the time-being. Comfortable enough, but not a top tier product--quality = pricing so I'm happy.

Answer: 3

Question: Note: Changed this review from 1 star to 4 stars after the seller reached out to me and issued a full refund (I did not even have to return the unused portion). This is good seller and you have nothing to lose by trying this product. If it works, then that's awesome. If not, you can get a refund. That being said, this product did not help our dog. We have a 14 year old female shepherd-hound mix who has developed separation anxiety. We were hoping these would help, but, although she enjoys eating them, she still barks constantly and gets very agitated when left alone.
