Product review (5 stars): Great price and I have had no quality issues over the last 3 years
Some reviews show concerns about these being genuine Samsung. I can confirm that the packaging has changed from prior purchases I have made. Not sure it's actually "Samsung" but the quality seems to be as good as the ones I used to get - and the price on these is great: seal is tight and I have had no leaks using 5 of these to date.
