They are worth the investment. I have had mine for a couple of years now and been through the learning curve with it. I used to go to a water store on the corner of Marbach and Hunt at night sometimes and worried about getting jacked as well. No more worries now, just need to hard mount it. I connect it and remove it from my outside faucet when water is needed. I think thats why I have problems with mt TDS readings, I can never get them to zero. The connecting, removing, and inconsistent pressure on the membrane is why I can not get a constant zero reading each time I make water.
