Bests & Worsts Reviews from Amazon

Update 11/4/18 Replacement unit lasted 3 months and it's now telling me to add pH when my test kit is telling me to reduce pH. This is the same issue others have complained about. There is also signs of condensation inside the unit which is what the first unit had before it died. I will continue to use it if I get a replacement, but there is no way I will pay for a subscription after the first free year of monitoring expires. Down to two stars since when it actually works it's very useful. Update 7/26/18 After a few email exchanges with customer service, I finally received a replacement unit. It was actually hand delivered to my home by Melly in customer service (I live near their headquarters). Looking forward to the 24/7 monitoring again. Hope the replacement unit lasts longer than the first one. Buyer be ware! When it worked, it was great. I scanned bar codes of various hth products and followed instructions in the app to add the appropriate chemicals. Mine lasted 3.5 months and I have been waiting almost two weeks for a replacement. Customer service will not commit to when the replacement will be sent out. Extremely disappointed especially since there have been mixed reviews. I now am questioning if I need this product since I'm now forced to maintain the pool myself. Not sure this product is fully developed and ready for consumer use.
