OK–Not GreatThere are “pros” to this bidet, including the seat warmer, comfort level, heated spray, and night light. But there are significant “cons” as well.For one, the dryer function does not aim properly. I contacted Coway support on how to adjust and was told by two technicians on two separate occasions that the dryer function does not work well, there is no waty to adjust the direction, and there is no fix(!)Also, about a year after purchase, we noticed that the unit was sliding on top of the toilet seat and discovered that the plastic bolts were stripped. I contacted Support again and was told to submit a request by email, which included the usual: name, phone number, serial # of product, problem etc. BUT I was also required to make a video, with sound, no less, showing the problem. Also, I had to VIDEO the serial number and product which, for the life of me, made no sense since that info was already provided. I also had to screenshot the “receipt” from Amazon.I few days later, I received an email from Coway stating that the “Management Team” would review my request and get back to me in a few days. About 10 days later, I received an email stating that “Management” had reviewed my request and that new bolts and nuts would solve the issue (ya think?) and how would I like to proceed.Actually, we had already replaced the plastic bolts with metal ones after not hearing from Coway for the first 3 days and knowing they would probably send us more plastic bolts, which would strip again anyway. The whole process for getting some plastic bolts was a colossal waste of time, and kind of ridiculous, TBH.Coway is a major brand for various items and the Bidetmega 400 is OK, but I really don’t recommend spending $400 for a bidet where the dryer function doesn’t work, at the admission of their technicians, and where a management team has to decide whether or not to send you some plastic bolts. If you want a bidet, go check out Tushy or Toto, or any other brand.

Was great…until it started crackingWorks well, it has good features, but after two years it is cracked in so many places.When using you get pinched by the top cracks. No one has stepped on it and our family is fairly small people.At this price point, I definitely want something that’s gonna last more than two years.

Plastic seat hinges crumbled after a year.This bidet worked great for a little over a year. The plastic seat hinges crumbled. There is no way to fix it. I got in touch with the manufacturer and Amazon. Both say the warranty is up so I am out of luck for a replacement or refund. Seems to be a very expensive bidet when you consider its short life. Many other reviewers mention the same deterioration of the plastic in this products.

Best bidet seatI was planning on buying another bidet seat which turned out not to be available for my area…I am glad because this Coway bidet seat is by far the best one.We have a Moen as well which is also a great bidet seat but the Coway one is by far the best one in overall performance.The water spray control (3) different modes, the fan also has 3 speed levels, the bidet cleaning, etc.We also bought a new toilet to go with this new bidet seat. Installation was pretty easy as well.Every home should have this bidet seat!

Love my Coway BidetMega 400E!!I’ve wanted a bidet toilet seat for years, but the recent TP shortage tipped us over the edge. Hubby says installation was easy. It came with several fitting options for water connections, and we had an electrical outlet nearby. His only minor gripe was Installation instructions came after Use instructions in a single manual. I’m OK with that, since this is my first EVER bidet seat I greatly appreciated & thoroughly read the detailed Use instructions.Key features for me were preheated water, self-cleaning, nice looking, and a reasonable price. I find the remote control reasonably intuitive and think this seat has plenty of bells & whistles without going crazy. Mainly, I am truly surprised at how much cleaner I am than with toilet paper. For a woman, this is more like the clean after your shower – Yay! Being cleaned with water takes a little getting used to, but I don’t see myself ever returning to TP only. The wash cycle is 1 min and the dry cycle is 2 mins. The dry cycle feels a bit long. I use a little TP to pre-dry before the dry cycle, and sometimes skip it entirely – your choice. I’d guess I use about 70% less TP than before.We have town water and have had no problem with the bidet water pressure. I use the medium pressure setting on the remote – it feels and washes fine. Hubby mentioned the Coway site warned if you had low water pressure this would cause problems with your bidet. I’ve used this for about a week now and truly love it. At first I thought I might use the Coway bidet as a short-term measure – until the price of the high-end bidet I had my eye on came down. Now I intend to stick with it long-term, it’s that good.A quick mention about registering the product online – for a 1 year extended limited warranty. Take a photo of the serial number on the back of the toilet seat, it’s hard to see once installed. I got several ‘invalid serial number’ form rejections. Turns out the serial number is printed on two lines, you have to combine them. The format that worked for us was: 12345 1234567 R1 (sample only)

Thin plastic seat may not accommodate average AmericanThe bidet itself is great, and the features themselves work well and are comparable to much more expensive models. I’d give it five stars for that.The problem is the seat itself. First, this is definitely a tight fit on most US toilets – mine met the size requirements but the opening extends almost beyond the rim of the toilet itself. It works, but you have to adjust how you sit on it.Second, I was concerned about durability the moment I opened the package, and for good reason. As far as I can tell the seat is just made of plastic, and it isn’t particularly thick. Maybe in Korea an above-average-sized person can sit on this without a problem, but I think anybody who is above-average size (even without being obese) would be likely to damage the seat fairly quickly even with fairly careful use. This device is awfully expensive if it only lasts a year or two, as was the case for me.The product itself doesn’t list any weight limits, but I’d be hesitant to use this if you’re over 170lbs, at least not without quite a bit of care. Below that I’m guessing you could treat it like any other toilet seat.It functions really well, and comparable Toto models are way more expensive. I have no idea of those are built any better. I’d be pretty hesitant to spend this much on a seat again unless it were built to commercial standards.I’m guessing it works much better in Korea where average heights seem to be much lower.

Not worth the moneyThe media could not be loaded.
I purchased this model in February 2020 at the start of COVID-19 after having to wait in long lines for TP. Initially I was very happy with it until I purchased a different brand for another bathroom. I didn’t want to spend another $550. I quickly discovered that the least expensive model, the Ivyel J-2R did a much better job cleaning for less money. So, I chalked up the Coway purchase, as live and learn.Then about 3 months ago, I discovered that the Coway seat cracked on both sides. See the linked video. I should say that both myself and wife are toned athletic people, so it didn’t crack due to heavy weights. I suspect it cracked due a combination of faulty construction material and heat as it had a seat warming feature.To the credit of Coway, the maker, who replaced the cracked bidet with a new bidet of the same model after doing everything in their power other than saying we abused it to suggest that we did. They suggested that if the seat wasn’t completely centered on the bowl, resulting in more pressure on one side could cause the cracking. My seat was centered, so that was not it. They made me take and send them many pictures and a (linked) video to prove no abuse. But what was the worst was that they made us go without a seat for about 3 days while they (Coway) waited to get verification of the shipment of the old seat before sending out the new seat. Luckily, I had an old seat in the garage, or we would either not use the toilet or buy a new seat to use in the interim.So, we have been using the new seat for a couple of months now and the other least expensive bidet is still the go to. And the real problem is that for the next couple of years we will live with the possibility of the new Coway bidet also cracking.

Broke after 8 months, but company RMAdI really love this bidet. Every single feature, except maybe the fan, but that was personal preference. But then the seat started cracking. Not just one crack, but everywhere. First the area around the feet and then the top seat along the edges & near the back where the hinge is.I’m disappointed in Amazon – I reached out and although they said they would provide support for a year, they marked it “beyond the time limit”** Update** I reached out to the company and they helped me troubleshoot. They ended up sending me an rma – a slightly different model that fit my toilet bowl better. The company itself has amazing customer service.

Mostly goodThe plumbing installation was simple but I had to watch the video to attach the seat as the manual doesn’t really show detail. The main thing I don’t like is how uncomfortable the seat is. Since the opening is small the inner edges of the seat really dig into my sitting bones. If you have a very narrow pelvis or a beefy butt, this may not be a problem, but it should cure a lot of people from reading on the toilet. The actual bidet functions are great, with a lot of options to choose from.

not as hot as I would likeIt gets the job done and I like it. I just wish the water and air was warmer.
