Amazing customer service and great products

I ordered the Founder's bundle. My oral care is markedly better, per my dentist and dental hygienist from using the brush alone. There have been some issues with the handles from time to time and Feno has been happy to replace them. Customer service is easy to communicate with and do their best to assist in every way possible. I find the value of the brush worth the cost by a margin.

I love the product and continued support and updates.

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.

I've left reviews for Feno before because I genuinely love this toothbrush, but I had to come back and write specifically about their customer service — because it deserves its own spotlight. A few weeks ago I sent them a simple, low-stakes email. My brush wasn't holding a charge the way it used to, and I was really just asking whether this was a known issue after about 18 months of use. I wasn't complaining. I wasn't demanding anything. I was genuinely just looking for information. The response was immediate — and completely blew me away. No runaround, no request for purchase records, no lengthy troubleshooting questionnaire. They simply told me they were putting a new brush in the mail. In a world where getting a company to acknowledge a problem — let alone actually solve it without a fight — has become an Olympic sport, Feno just handled it. Quietly, generously, and without making me feel like I had to justify myself. This is what customer service is supposed to look like. They stand behind their product and they value their customers. Highly, highly recommend — not just the brush itself, but the whole experience of being a Feno customer.

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.

This thing is actually awesome. At my last dentist appointment, I had my best gum checkup ever. Finding the right mouthpiece fit is easy. One thing I didn't know I would enjoy would be the time saving aspect of this toothbrush. Over the course of a week you save: 21 minutes, 30 day month: 90 minutes, Year: 1,095 minutes, which is 18 hours 15 minutes. That's a freaking win in my book. only complaint is the tooth paste. The straw does not reach the bottom making it difficult to get to the last part of the liquid.
