I had an issue where my UV staying on and I called support and got a man named nick. he knew exactly what was going on and is sending out a replacement part. RO unit is great and service is also great.

Great customer service.
I've had an iSpring RCC7 since 2018 and it's been great. However, some of the older alkaline filters I received have had leaky seals, but their customer service is consistently fantastic and Sean helped me get replacements for the leaky alkaline filters. Their phone lines are only open during normal US-East business hours but that's because you talk to actual people based here in the US and they're very understanding. Would buy again!

Outstanding Customer Support
We’ve had the iSpring under the sink 5 stage system for three years. It’s been a great addition for better health. I ordered this filter for the annual replacement. The new unit leaked from the easy connector. I called costumer support at iSpring and talked to Michele. She suggested it could be due to a damaged o-ring. She ordered and shipped a replacement for me at no additional cost. Customer support is outstanding. I highly recommend iSpring systems.

Good product, sealed up well
Two of these (instead of one) should be included in the "1 year" filter replacement kits which contain 2 of all the other filters (except the RO unit). This has been quite bit of annoyance since I change all 5 filters (stage 1, 2, 3, 5, 6) on minimally used once a year and the RO unit (stage 4 I believe) every two years. So this causes me to buy one of these every two years (along with the RO filter).The unit arrived well packed was all sealed up and included a parts kit.I have to knock off a star for the annoyance of iSpring not including 2 of these instead of 1 in their water filter replacement kits.

Good flavor
We have a well and I use this on my reverse for our drinking water. It’s better than bottled water.
