Great product. I had one on another pool for years and never had any problems. I recently purchased a new one with the see through canister. Easy to see when additional chlorine tablets are needed. Incredibly easy to self install! I highly recommend the Rainbow Chlorinator

Have had this for years and has always been great. Through my own fault I broke it after probably 12+ years of use. I ordered one and put it in myself and this is not the first time I ordered from this company and they ALWAYS send what I order on time, new in the box and no mix ups. I recommend this product and this company.
