First, I received this product 3" tablet (50 lbs) but there were about 15 tablets got damaged due to shipping from FedEx. I called and complained about the packaging process to prevent the future shipping. The agent immediately noted down, and offered a full replacement! He was very professional and apologized for what happened. After a few days, I received a brand new replacement ! I totally didn't think they will do that, but they did!!
Also, the product was very good after using for 2 weeks. I have used different brands like Leslie or IntheSwim, and this Doheny's tablet is the top quality!! It is making my pool clean and fresh!
