Best customer service
I had a problem setting my new improved control board. The really nice girl in customer service set me up with a technician who was also very friendly. I would give them 10 stars if I could.

Perfect fit
A power company goof up pushed 185 volts into our house instead of 120 without any notification for over 2 hours. It burnt out the furnace transformer, the power board on our TV and the controller board on our water softener. Thankfully, the water eStore had the controller board in stock and got it to us in just over 2 business days. It has been working flawlessly for several weeks now. Their customer service is outstanding!! Highly recommend.
