    Wonderful product. Individually wrapped and not crushed like many companies send out. Tablets seem to have a sealer on them to keep them from disintegrating. Check it OUT!!

    I have owned pools since mid 80's and the tablets from National are the best I have ever bought.

    For many years I was buying tabs from another online store. When that company ran out last summer I gave National a shot. Super fast shipping and the quality was as good if not better. Will buy again
