I have bought this product several times

I have had two shipments of this product in the past and found many broken tablets upon delivery. However, my first shipments and this last shipment was received with the tablets all intact, as far as I can see. This is a very good product for maintaining the chlorine levels in your pool.

Great Prices for Great Products!

I have purchased Doheny's Tri-Chlor tablets several times. I have a 25,000 gallon pool and it eats all chlorine tablets up in the summer time. Tri-Chlor is the best product I have found for pool maintenance, and Doheny's 50# bucket of 3" tablets is the most economical way to purchase them. The bucket comes in a manufacturer's labeled box and is usually delivered within days of the order, with free shipping. I have compared the pricing on many brands, sizes and distributors, but have found the Doheny's offerings to be the best. I will definitely buy from them again!

Great Delivery

This is the thrid or fourth time I have ordered this product. Look, chlorine tablets are about the same sold across all the major dealers. There is not a of difference between Doheny's and Leslies. The big difference?" Delivery to my front door within 36 hours. That is a service I appreciate - the fact that the last order was $20 cheaper than Leslies just made it sweeter.
