Speaking from Experience with a neighbor's Shasta pool, A&A stuff is generally decent quality, but it is also very proprietary. You'll be stuck going to Shasta for support and they have you by the short hairs, they can charge whatever they want. Their Lifetime Warranty sometimes is a bit misleading. Read the fine print. I do not have specific experience with the Quickchlor, just experience with other Shasta (A&A) products
