[Q]: The item was delivered in good condition but when used on two different USB ports on my Samsung flat screen tv to power a fire stick device ,a message was displayed saying not enough power for this device.
[A]: negative


[Q]: I have been using this exact brand and item but bought at Ulta. They are great. I got months of wear out of them. When they no longer carried it I ordered it from here. I got 2 pairs. They both did not stick to my skin at all. They couldn't be worn.....fell right off. I found them at CVS and did not have a problem with those. This was supposedly the same exact product. I'm not sure what to think but I would not recommend buying from here.
[A]: negative


[Q]: I bought this as a second set for my Ameda pump. It fit perfectly and I washed in the dishwasher before using. All parts were of the same quality as the original one.
[A]:
positive
