Review on 📊 Impressive Accuracy: iSpring TDS 3-Button Digital Water Quality Test Meter with Temperature Test Function by Lindsey Lewis

I was hoping to find out if I needed to replace my 7 stop filters. Instead, I'm more confused and less informed. NO INSTRUCTIONS for one. The readings are very limited and unclear, not to mention that the numbers do not differentiate between tap water and filtered water. If I hadn't let taste guide me, I wouldn't have believed the system worked. The fact that this is made by the same company as my filter system makes this even more unfortunate as you would think they would try to highlight the major improvements their system has made. All in all I would not buy this item again, it's a waste of money.
