Description
Neptune Trident Reagent 2Neptune Trident Reagent 2 Overview A two month reagent kit for the Neptune Trident water analyzing system. The cost of reagents and recurring cost is a valid concern for a hobbyist considering the test kit or automated system and we designed the Trident with that in mind keeping those costs as low as possible.

it is used by our Eufy E25 and since the cleaning is done well I suppose this product does its job well.

Best investment!!!
Size: 16 Fl Oz (Pack of 1)
Highly impressed after using this in my new home for several weeks. She saves me 1 1/2 hours a day keeping up on my floors-2700 sq feet, mostly laminate wood but I love walking into my primary bedroom and seeing her vacuum lines too! I get maid service daily!!! Still have to do edges, corners and be hind doors occasionally- but I wouldn’t be without my “Rosie Jenson” IYKYK😊

fits and works for s1 as well
Size: 16 Fl Oz (Pack of 1)
I bought this for my omni eufy s1, and it fits. For some reason it doesn't confirmation of it clicking in place.
But it has the same exact size and shape as the one being sold for exclusively for the s1. All you have to do is take off the stick, push it down, and then push it in.
So it fits, it just doesn't give auditory confirmation when you're putting it into the base station. Which is weird but whatever. I got this because it was $4 buck cheaper then the other one they're selling.
