Bests & Worsts Reviews from Amazon

(Updated to address claims for 1 month and 3 months) I live in a very small house where there is no room for a full house water softener, so I decided to try this descaler. I placed it on my PEX pipe right before it branched off to its various locations, all well within the 50 foot limit, probably within 30 feet. The installation was simple, as others have mentioned. The most difficult part was laying in a small crawlspace while winding the wires around the pipe. Day 1: More lather - This is the first time I've seen lather since I moved here and this was with the first shower after installation. I knew at that moment that the descaler was working. Week 1: Breaking down scale on water heater heating element and water pipes - My water heater is only a year old, but was losing the ability to maintain hot water. After one week, this issue has been fully resolved. No more lukewarm showers. Week 2: Loosening of scale on faucets and showerheads - My faucets are no longer developing stalactites, and sink drains are not coated with white, crusty film. 1 Month: Less time for water to heat; reduction of scale on showerheads, pipes, and faucets - I see a noticeable reduction in scale on my showerhead and faucets, and have had no need to clean them beyond general cleaning, no more scraping away crust. I've also seen a significant amount of scale come out of the faucets (I remove and check monthly, with the first month resulting in large chunks of scale). 3 Months (I'm addressing just 2 months in since these issues have already been resolved): Disappearance of scale from showerheads; scaly crust in toilets is significantly reduced and no new crust should form - True on both claims. The most amazing was the total disappearance of scaly crust in the toilet, which has been an annoyance since I lived here. It looks brand new now and requires only normal cleaning. I am very pleased and surprised at this simple solution. This product has resolved a handful of issues that I've had with hard water. Without room to install a water softener, this little gadget has saved the day.
