This does not work on every device as stated. I purchased this for my Kindle Fire HDX. It does not work on Kindle. This should be stated in the description, but it isn't.

I purchased these in 2012, and found they will definitely help me keep the unused wine a lot longer without trying to stopper the bottles with the cork the bottle came with. For an amateur wine enthusiast like myself this was a great help to allow the wine to be kept away from air that will flatten the flavors of the wine. It's not rocket science, just pump and listen for the 'pop', which tells you the vacuum is good inside the bottle. Lasts a while, too. Of course if you keep more than a bottle or two, have more than a glass or two of wine every so often, one should get two, three or more of these. I am reordering, most definitely and will recommend purchasing these to anyone who likes wine, cooks with wine, or.....? A no-brainer.
