Trust me, this is a dangerous product and should be removed from desertcart! but hey, desertcart refunded me so... don't put yourself through this nonsense... Trust me, not good! Review: Don't buy. - Absolute garbage! The chlorine was broken internally and all over the inside of the wrapper. When installed, all of the chlorine was dispensed at once.
