FenoReviews of feno.co

Too hard to use. I just threw it in the trash. They want you to spend $8 to get some daily evaluation. I just want to brush my teeth.

Ordered over a month ago and have yet to receive any information on my package. Also the tracking link on my package just stopped working and when I try to track it via the feno website, it’s says order not found. I am baffled by the lack of honesty and communication.

Zero stars if I could. I ordered from Feno over two months ago. After waiting with no updates, I was finally told by their customer experience team that they were dealing with a "temporary stock issue". They tried to smooth it over by offering extra Feno Foam, but it's been over two months now and the item still hasn't even shipped, with no communication in between. It is completely unacceptable to take customers' money for items you don't actually have in stock to fulfill. I have officially requested a cancellation and a full refund. Avoid this company unless you want your money tied up for months.

This is my second review. The first one explained how feno's blinkered focus sells to everyone as if we are all in the US, but anyone buying outside the US will not get the same treatment. Everything they post takes months to arrive. The most recent shipment still hasn't arrived 2 months after it was sent. This is no longer a problem as I am no longer using the device, but it's a good indication of the inefficient service they offer. So why a second review? When you buy a feno they give you this whole story about an AI scanning process that can accurately measure which mouthpiece personally fits you. This turns out to be a process where they take a photo and then manually guess. I got sent 2 mouthpieces with the original purchase, neither fit correctly. I asked for sizes but they refused and then sent another mouthpiece that also didn't fit. They then sent the actual measurements by which I could see why none of them fit, and the last choice of mouthpiece size was posted (the item that has never arrived) So during this multi-month-long waiting process, I was using the best fitting mouthpiece that wasn't quite the right size, did not account for overbite misalignment between upper and lower teethlines and it damaged an implant that will now cost me about £4000 to fix. My implant was not lose beforehand, but it is now, caused by the shaking motion. There's nothing worse than spending so much time, effort and money to improve things, and the knowing that your own decisions have made it worse. So you should be very careful when considering whether to use this toothbrush. It's basically a mouthpiece that's being shaken from side to side, there is no 'intelligence' to it, especially when it comes to mouthpieces. Their claims of matching shapes and sizes to a large dataset appears to be complete sales talk, because none of the mouthpieces I was sent even reach the last molars, all of them might be suitable for 28 teeth (perhaps thats a norm in the US) but they do not clean all 32 and they basically have 5 fixed size options. All mouthpieces I was sent assume a perfectly aligned bite, and if you have an overbite the pressure is not as intended. I didn't write this review straight away because I was so angry. If I lived in the US I have no doubt I would be suing them for damages, and I consider they got off lightly by just giving me a full refund, but that does not come close to the dentist bill I now face to repair the damage. In summary, for me a complete financial and dental disaster. If you already have strong health teeth and a perfect bite, this idea might work for you. If you have overbite, implants, other structural dental work or anything lose in your mouth I would recommend you stay away.

I ordered over a month ago with a promise of delivery within 3-7 days. Now they still have not shipped my order. Their support is useless. I have asked for a refund twice now and they have not responded. On top of this, you have to pay a subscription (which I also had to pay before them shipping). Overall awful experience.

Great product in theory, but falls short. Mouthpiece is very large and uncomfortable, and actually made canker sores in the back of my mouth from the friction of the mouthpiece the very first week. Even turning the vibration setting to low for 20 seconds still create the same friction areas. 8/10 Cleaning. Often times will miss spots I can still feel plaque on. Sometimes need to brush twice in a row in order to get that clean mouth feeling and all of the plaque off. The app 0/10. This is where the product falls short the most. Scans are simply photos of your mouth you take yourself. Wildly inaccurate! Used my product and it said I had multiple cavities, plaque, and tooth fractures on the first scan and more issues would pop up with each consecutive scan, giving me a lower dental score each time. And it doesn’t tell you specifically where these “lesions “are, only the side of the mouth they are located on. I immediately made a dental appointment and had none of those issues at all! The dentist actually saying that I had “superior dental .” The app created so much stress and made me super insecure about Poor dental health and negatively impacted my self-esteem for an entire three weeks. Additionally, the fresh breath score is totally off despite using it for three weeks consistently 2 to 4 times per day I’ve never gotten over a 50/100. Product OK at best, app is total garbage and if anything negatively impacts your overall well-being creating a false sense of insecurity.

I had a very disappointing experience with this company. I requested to cancel my order before it was fulfilled and clearly explained the reason when asked. After that, communication stopped. Emails were not answered, and when I tried calling, no one picked up. Instead, I received an automated message saying phone support is unavailable and to contact them via text or email — which I had already done, multiple times. Despite following their instructions and providing everything they asked for, I received no confirmation of cancellation or refund. I was forced to open a PayPal Credit dispute just to protect myself. This experience caused unnecessary stress and wasted time. A legitimate company should not ignore customers once payment is made, nor make support inaccessible. I would strongly caution others before ordering. Tugba ugurlu
