My parents got me this system as a housewarming gift and it’s been great! The tap water right now tastes like lakewater due to the algae bloom in the local reservoir, but this machine makes it taste great again and quickly dispenses hot water for ramen and tea. Setup was as easy as finding a spot on the countertop, filling the water tank, and plugging it in. The instructions are clear, and there are a ton of options for how much water to dispense at a time and water temp (including a formula temp for mixing baby formula). I’ve replaced my zojirushi water boiler with this since the hot water function is integrated and so fast. The only thing I wish I could change is to make the dispenser height a little higher so that my sodastream bottles fit underneath. Right now it’s just a quarter inch short so I need to pour the water directly from the pitcher into the sodastream bottle (first world problems, I know). Overall, it’s been great and made me want to drink plain water again!

Great countertop unit, owned for about 8 months and loved it for every moment. The best part is to know you have a company to stand behind, recently reached out to Sean about a filter order and he was responsive and followed up with me until everything was resolved. Amazing product, Amazing company. Thanks Sean.

I bought the iSpring RCD100HCG to stop the weekly routine of driving for bottled water, hauling cases up the stairs, and tossing 10–12 plastic bottles a day. This unit has been a solid investment. It’s plug-and-play easy, looks great on the counter, and the canisters are lightweight, durable, and genuinely well made. What I love most is the control it gives me: nine temperature settings and six dispensing volumes, plus a clear TDS and filter-life readout. It’s simple to keep tabs on quality and maintenance. iSpring’s sales, service, and support have also been excellent—fast replies, helpful guidance, and no runaround. I value buying from companies I trust, and I’m glad I chose iSpring. Before moving to a condo, I had a whole-house filtration system. The RCD100HCG brings that same “industrial” confidence to a household countertop unit. Based on what I could find about certifications and build quality, iSpring stood out from other look-alike products and met—or surpassed—every expectation. Trade-offs: The only minor compromise is refilling the reservoir—anywhere from a couple of times a day to a few times a week depending on usage. For me, that’s a small price to pay for the savings on gas, the end of lugging water, and cutting way down on plastic waste and garbage pickup. Bottom line: If you want clean, great-tasting water with real temperature and portion control—and you value trustworthy support—the iSpring RCD100HCG is an easy recommendation. I’m extremely satisfied. Thanks Sean for your incredible support!

We are renting, hence we can’t install an RO system under the sink. This system was the perfect solution! Our city water tastes and smells like it comes from a swimming pool, but when we run it through this RO system, we enjoy the taste and feel confident in drinking it.
