Express Water Elite RO Reverse Osmosis Alkaline Water Filtration System – Quick Twist Filter Change 9 Stage RO Water Filter– Under Sink Water Filter with Alkaline Filter for Essential Minerals 100 GPD

Very happy with the Express Water Elite unit. I purchased this because it was slightly smaller dimensionally with the tank and more compact filters than the other Express Water units. Took about an hour or so for installation. Water tastes great and we should have ordered a RO system for our house many years ago. If you are looking for better tasting water or to remove chlorine or fluoride, I’d definitely recommend. They say the filters last a year but other systems say 6 months, so I guess we will see how long they last. Still worth the money. Water is so important in your overall health!

Very easy to install, occupies small space under the counter, water checked between 70 -30 which is expected for ROS given the added solutes, highly recommended

This is my cooking and drinking water.The flavor of coffee is better than most restaurants. This is designed so well.Very easy to change filters.

Update: After all the hell I dealt with trying to get this company to back their product or even follow through on what they said they would do, I finally resigned and sent the unit back for a refund. This also meant having to patch up the damage to my sink and pipes made when drilling holes in order to install the unit, and I'll still never receive reimbursement for the $300 I had to spend for a plumber because they wouldn't help with locating the proper fitting. Anyway they said the only way I can receive the refund is by check since it was purchased on Amazon. It's been like three weeks since they said they sent the check and I still have not received it. They said there's no tracking number or anything so I can't even verify that it was sent. And now they are no longer responding to my emails. Worst company I've ever dealt with outside of the government.The fitting(s) they include for the cold water line did not fit the hoses/attachments under my sink. I tried going to Home Depot and finding something on my own, but I couldn't get help from employees and the closest thing they had in store ended up leaking when I attached it. After getting on the phone with customer service, they told me if I sent pictures they'd have their 'in-house plumber' contact me the next day. They never did, so I called. They said he wasn't back and they weren't sure when he would be. I waited 2 more days and tried again, and they told me the same thing. When I pressed for more information, they said they would find out when he'd return, and ended up telling me there's no way to know and sometimes he can be gone for up to two weeks at a time. They recommended I contact a plumber. I stated I wasn't happy about having to spend a couple hundred more dollars when they advertised this system as being 'easy to install'. The only other option they offered was a refund, but after spending as much time as I had already getting everything else installed, I wasn't willing to take it all apart again and ship it back to them and then go through the same process with another company. So the attractive price you see here is not the cost of the unit, unless you get lucky and one of the two fittings they include with the unit happens to fit your system, and there seem to be many cases where it does not. At this point, I can't speak on the quality of the water or anything else since it's been almost a week and I'm still trying to get the stupid thing installed. Hope your experience is better than mine.Update:So I ended up having to hire a plumber and spending another $300 just to get the machine connected to my water line. On top of that, there was an unpleasant aftertaste even after draining and refilling the tank numerous times. They instructed me to drain the tank while it was upside down a few times. That did seem to improve the taste but it still has an unpleasant aftertaste. We'll see if they're willing to help me any further or if this is the best that can be expected from this unit. Based on my experience so far, I would not recommend this unit.

My husband was able to install easily within an hour. We have been testing the water with a tds tester and I’m glad that it has been testing from 33-56ppm. We have emptied the tank over the past day I’m hoping it will be lower than 31ppm because my mother in law has a really old water filter with three filters and it tests at a ten. I will be so sad if 31ppm is the lowest with all these filters. Without the water filter my tap water test at 500ppm and my mother in laws water tests at 600ppm. We had purchased a water drop before this and returned it because literally made no difference in the water. So this is a step up but I’ll keep my figures crossed because I like how easy it will be changing the filters out by screwing on and off and it being once a year.

Super easy to install. Replacing a system that costs 3 times as much and like this better so far.

UPDATE: after numerous emails back and forth, being told I needed to buy expensive mineral drops to alkalize my water, providing pictures of the install to prove I followed directions, proving that I bought this direct from their website to later be told I bought it on Amazon (mind you I was replying to THEIR order confirmation email from their site), they decided to send me replacement cartridges. Basically I had to resort to carefully worded messaging imploring that they stand behind providing the product they advertised (if you catch my drift.)I'll admit by the time I was done dealing with the polite yet supremely less than sub par customer service experience I didn't even bother reading their final message and threw the new filters in storage. Pretty much at this point I'm going to burn through the filters that came with it, manually alkalize my water, use the replacements next year, and just get a different system after that. Ease of use shouldn't come at cost of advertised and promised product performance.Final verdict=Not worth the price IMO. Doesn't actually end up alkalizing water. Talk to a local professional to get a proper system instead of one of these one-size-fits-all kits.===============ORIGINAL: I've already reached out to the manufacturer directly because I purchased my Elite RO directly on their site. So I will update if/when I hear back.First image with the two test strips (I know not the most scientific) show the RO water on the left strip and the regular tap water to the right. Other than being slightly less chlorinated and softer the pH/total alkalinity is off the chart to the acid spectrum of my test strips.The second image I took was after I shut off the system and released the ALK filter and poured that water into a clean glass. You'd think the water directly poured from the ALK filter would be as high on the pH scale as one could get. At the very least you'd think it would be higher pH (if even slightly) than my municipal water source. Not so. I've had this unit installed for 27 days thus far and for nearly a month it would appear I've been drinking acid water.To make sure my test strips were working I mixed 8 ounces of the filtered water with a ½ teaspoon of sodium bicarbonate and in the 3rd image you can see it jumped to the alkaline side of the chart and pH registered max for the test. Either I got a faulty unit from the manufacturer or their selling everyone purified acid water. I could be wrong on both fronts I suppose, but I think I'll go back to tap water until I hear something from their customer support team instead of an automated response email.The fourth image is tap water on the left, filtered RO water in middle, and pure lemon juice on the right. Both the filtered and lemon are beyond the scope of the test strips for acidity but you can see apparently lemon juice is considered "hard" water lol.Each round of testing was done with a new strip each time and new glasses to prevent any cross contamination in the test results.
