People are complaining of lower poundage on chlorine . Its 10 lbs less and $40- $60 less , same price per LB. Its by far the cheapest you can buy.

Believe this product has stabilizer in it. After using my stabilizer reading went from 60 RPM to 250 RPB.

Having to unpack each one just puts you in contact with more chlorine longer. There is always residue on the outside of each wrapper. I don't buy these anymore for that reason.

Saw some bad reviews, mostly good, tries these out, WAY better than national pool supply stores. Hugely less expensive, does a great job. These, used properly with good maintenance are outstanding at almost half the price.

I have been using these for two years (since I got my pool) and my pool is alwaysssssss nasty!!! I have now decided it’s the chlorine that is making me fight my pool- it’s not working!!! $100 more this summer down the drain on them.

Even with my chlorinator set to 1, these dissolve quite fast. And, probably about a third of them are broken up inside their wrappers. Sort of frustrating that so many are broken.

NOT STABILIZED!

I have no place to store this inside (machine shop in garage, wooden cabinet rotted, rusted the hinges and springs on the Sam's plastic storage locker). Harvey dumped 36 inches of rain and filled up the bucket with water which came in through the ratchet lock. Other brands do not have this problem, the lids are sealed. I had to get a gas mask on to open the container. The bags all had water in them.

For my Spring start up, I placed the usual number of tabs in my dispenser plus threw granules directly into the pool. The chlorine level in my pool remained undetectable no matter how high I turned the dispenser up. I did have 2 tabs left over from what I had bought last year (PoolBrand, from Sam's) and threw them in my dispenser. Within hours, the chlorine level shot up. The new Member's Mark tabs are worthless. Thankfully, Sam's has such an easy return policy.

Chlorine is chlorine, right?... all pretty much the same. Nicely priced compared to pool store. My gripe here is the each individual tab is packaged. Why?? Not only is it a pain at the pool with wet hands and no scissors handy, but do we really need to add more plastic waste to the world? Do better Sam's.
