I have an iSpring 5 stage reverse osmosis system and I LOVE it. Love love. Just because I love the system as a whole so much this part gets 3 stars. It can be made to work, but this requires additional details and a little trick. That's the problem. If you buy this, you must also order this. SHAY Essential Pro makeup train. https://www.amazon.com/dp/B07D629S7W?ref=ppx_pop_mob_ap_share I thought I could just keep the connectors from my old Stage 5, but this one actually has the connectors built in. Now that I've bought them separately I can save and reuse them every time I change the filter so it's not the end of the world but it's quite annoying that the parts needed to make this thing works, don't come with her.
