Apparently protects against calcium deposits. Softens water by up to 70{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} by using magnetic power to crystallise limescale and last up to 10 years? 😯
Look like Ecoballs in another guise Martin although I’ve not seen that version before. Quite what the point of a squared off ball is I’ve no idea, looks like something you’d see on the Flintstones.
