Broken tablets

It's nice that these tablets are individually wrapped but almost every single one is broken into a million pieces. I'm sure they will dissolve much quicker since it's basically in powder form. For the price I expect intact tablets.

Top notch container

These pool tablets last us a year which is a good thing but having to pay an increase of 93% verses last year price was a real shock. Container top quality and each tablet is warped individually. I gave it a 2 star due to the price increase.

Good quality

I bought these tablets on 7-14-15. They ARE individually wrapped. I ran my filter over night with 3 tablets in one of the skimmers and they are about half dissolved as I would expect. They are the best value I could find.

Bad chemical Burns from tablets.

We have had our pool for twenty three years. i bought these tablets this year and they give both of my children and the neighbors children really bad chemical burns. Ireturned them for a refund. they also irritated the adults, eyes, nose and mouth. i would not recommend buying these

Used to be good. Contaminated tablets clogged feed

I've purchased this before, but this last purchase has been horrible. I spent the summer trying to figure out why the chlorine feeder wasn't working well. Got a new feeder even. Now discovered that the tablets have contaminants in them that clogged the valve and feeder tube. I will contact Sam's for (hopefully) a replacement, even though I have gone through half the bucket in the process.

CLORINE TABLETS

Like the way tablets are individually wrapped, they dissolve nicely and are working well.
