[EX Q]: This Game does not give me any direction to work the app. I have it on my phone and am addicted to it, but cannot figure it out on my Kindle. It may be wonderful if it works, but have not been able to figure out how to do anything with it . So disappointed.
[EX A]: negative

[EX Q]: When the ache/pain in my upper back won't stop, I always turn to this product. It takes away the pain almost immediately. It is adjustable and comfortable to wear. I love it!!
[EX A]: positive

[EX Q]: I bought this clock a little over a month ago and it's already not working. For the past few days, the hands have been randomly stopping, but they would start up again when I picked it up off the wall, as if they were just getting jammed. I thought it may have been the battery so I replaced it but it didn't make a difference. Also, it may not tick, but it does make this sort of weird scratching sound, which is very easy to hear when there's no other sound. I honestly wish it would've broken earlier so I could have returned it, but I am now two days past the return window. I am not normally one to leave bad reviews, but I'm pretty annoyed that I spent almost $30 on something that broke after only a month and I can't return it.
[EX A]:
negative
