I replaced with the outstanding SimPure T1-400UV Tankless RO system and the water is so good, my kids dropped from 3 artificially sweetened drinks (intolerant of the "buns" tasting water) to 0-1 per day. The only issue was the flow was noticeably/annoyingly slower. The specs on the T1-400UV say it is 0.27 Gal per minute, and mine measured a little faster at ~0.37 Gal per minute on a short fill. I added this tank and speed shot up to 1.1 Gal per minute. It takes up minimal space under the sink, but holds 1.4L in reserve to crank out at 1.1 Gal/min which covers all my water and sports bottle volumes. So if I was filling up more than 1.4L, it would drop back down to baseline flow, but anything under is true max flow. I don't have it hooked up to my ice or fridge, I just got it to increase flow. Of note, it would work with any water filter, not just SimPure, and just hold that higher-pressure 1.4L in reserve.
