What it does for your water
The Mineral Magnet II TWI-5001 Electronic Water Descaler is an electronic descaler that works on the pipe from the outside.
Like every salt-free option, it leaves the hardness minerals in the water: a test strip reads the same afterwards, and the maker's claim is about scale, not softness.
Electronic units need a power outlet near the pipe and work only on the pipe they are wrapped around; the maker lists which pipe materials and diameters suit them.
The listing also gives model TWI-5001; warranty 5 Year Limited Warranty.
The listing gives dimensions of 4.3 x 3.3 x 1.5 inches, a shipping weight of 1 lb and two polypropylene housings, two nylon bolts and two nylon wingnuts in the box.
Warranty, per the listing: 5 Year Limited Warranty.
