[EX Q]: This was bought as a Christmas gift for my daughter and son-in-law to use when they go camping. The box was not opened until July 13, 2019 when they camped. One whole row of lights does not work. I wanted to know if I could get a replacement si ce this does not work and it's the first time it's been opened or used?
[EX A]: Could I get a replacement since this does not work and it was a Christmas gift ?

[EX Q]: Very excited for this till I got it to realize it's way to small for the amount I need to grind up.

[EX Q]: Sound quality is alright--for about 5 minutes; the headphones volume cuts in half within a few minutes of using, to the point your music is nearly inaudible in a room with ANY noise in it. This is from a FULL battery, mind you. I looked through reviews and didn't see this point, so I'm thinking I may have gotten a defective unit that can't deliver proper voltage from the battery during usage. In any case, I'm very disappointed with my purchase.
[EX A]:
Inconsistant sound/volume makes these a poor choice
