Worst customer service ever
It seemed like it was reducing my snoring a little bit, but the mouthpiece automatically deactivates after 90 days. After spending about $1000 for the device it’s annoying that you have to buy a new $150 mouthpiece every three months. If you can get one. I ordered mine a month ago, haven’t received it, and can’t even get a reply to questions about it.
Mouthpiece on backorder almost 4 months.
I ordered a replacement mouthpiece 5/3/2024. Today is August 28th & I have yet to receive the mouthpiece. For months I've been told they expect to receive stock in 2-3 weeks. I kept my order in place when advised they would "extend" my mouthpiece. Fine, this worked a few times but now it won't connect at all. The only reason I gave 2 stars instead of 1 is because I believe the device works. Unfortunately without a functioning mouthpiece it's useless. I'm wondering if Signifier is being transparent about the reason for the backorder. I read that last June they received their largest commercial order ever, 10,000 units from a company called Spectrum Sleep Solutions. So current users are put on the backburner??? A little suspicious...
Don’t buy this product! I was happy with this product until I…
I was happy with this product until I ordered the replacement mouthpiece. After four months of waiting I contacted the company for a reimbursement, which I did receive. It’s very disappointing that I had this product for less than a year and now can’t get the mouthpiece replaced that they said I needed to replace. This was a very expensive item that I was hoping to use for the rest of my life. After reading some other reviews, I realized that I wasn’t alone in my frustrations with this company. Don’t spend your money here. This company is not reliable or honest!

Amazing Company with a Product That Works
Excite OSA is an amazing company with a product that works, Using this device has been a life changer and it’s so easy to get any Question answered at any hour via the app. Highly recommend!
Snoring got worse
According to my sleep tracker, after over a month of use my snoring got progressively worse. I was snoring over 50% of the night. Also, my wife said that not only did the frequency increase, but the volume increased too. This is an extremely expensive device to have such lousy results.

Out of stock for over a month
It was working, and I was very happy with the device. However, mine is coming up for renewal, and I ordered a new mouthpiece over a month ago, and have been repeatedly told they are out of stock. Is the company still able to provide a service? I'm still awaiting an adequate response for a something I have spent a lot of money on. Customer services have been very polite, but I'll be unable to use my device in under three weeks.
I was offered a time extension on my mouthpiece. I was lead to believe that it must be replaced - is this not the case, then? I understand the need to fund the product, and am happy to do that, if it is something that's works, but this just seems dishonest.
In all, I've been very happy with how it works, but I'm extremely unhappy with the response I've had. I've tried to address this with customer services first; this review is just about supply issues and the length of time it has taken to receive something I have paid for.
EDIT: Now four months later, and they are still unable to fulfil back orders. I recommend everyone avoid this company until they can sort their business out.

User Friendly & Very Effective
I used a CPAP machine for nearly 3 years. Extremely unhappy with it. I spoke with my sleep clinician that I would like to try Inspire device. After hearing the details I quickly lost interest. Fortunately she recommended the eXcite device. Easy to use & very effective. Finally I'm sleeping like a happy baby 👶. I wish I had known about the eXcite device 3 years ago. It would have prevented 3 years of misery with the CPAP.
Didn't work for me!
The product itself functioned as promised, with its great app, clear instructions, and solid build quality ticking all the boxes. Both packaging and delivery were very good, and the customer service deserves a nod for its excellence. However, despite my diligent adherence to the instructions, the device failed to address my snoring issue. I monitored its effectiveness using a sleep tracking device and received feedback from my partner, but unfortunately, there was no major improvement. Additionally, the replacement mouthpieces are expensive. So for me overall it was not good value, and definitely not a long term solution. I have since found non-device techniques, such as adjusting my diet, modifying my sleep patterns, and incorporating mouth exercises, to be more effective in addressing my snoring issue.
I tried this machine
I tried this machine. The shock on the lowest was unbearable. I can’t imagine the long term side effects. I am returning after one use. My tongue is really sore

My Girlfriend likes it!
I have recently tried this product and it has been a few months of use. My girlfriend says I snore less so it has been great for her. I sleep no matter what. 😂 But as an added benefit I also feel more restful once I started using the device, more oxygen in, and less snoring out….winning!! I can’t claim to understand how it all works but I’m grateful that a friend recommended this to me. The app is easy to use and the reminders are great. It will help you develop the habit of use.
It works!
My husband has been using this device for several years and it has helped tremendously. A few months ago, his charging unit quit working, so he went without his twice weekly treatments for several weeks. His snoring got worse. They sent him a new one and it i proved again. Thanks eXciteOSA!
Awesome results
My wife is using this for moderate obstructive sleep apnea for a little over a month now. Her snoring was super loud and kept me up at night. Now it's radically reduced to almost nothing. This is a Godsend to me. Not only is it great for her, but I'm able to sleep so much better.
DON'T BE FOOLED
This may be great for sleep apnoea but don't be fooled by the adverts as it has doen nothing for me for snoring
Absolute life changer
Absolute life changer. I used to wake up unable to breathe every time I slept on my back and so tied all sorts to my back to keep me on my side at night for two years. I had tests and was diagnosed with sleep apnoea. The consultant recommended eXciteOSA. I did the initial six weeks before I dared trying to sleep on my back again and haven’t woken up gasping once since. I’ve been on twice weekly treatment now for a couple of months and am still sleeping great. This has made a huge difference to my sleep and my daily functioning. I’d forgotten what a good nights sleep was like. The device is really easy to use. It feels fairly painful on high power at first, but over the first two weeks I was easily able to increase the power levels without massive discomfort. Now I am completely used to using it on full power all the time. The support / helpline / chat function on the app have all been great. I’ve felt supported throughout. I had a small problem with interference from a new Fitbit and the helpline sorted this straight away. It’s a small price to pay for not being afraid of sleeping and not being deranged with tiredness during the day. I couldn’t recommend the product highly enough.
Excite OSA's Customer Service
Excite OSA's product works. I have sleep apnea and cannot use the cpap machine. My sleep doctor at Mayo Clinic told me about the program at Excite OSA, so I decided to try it.
A program is only as good as its support. The program provides users with information about sleep during therapy sessions. Most importantly, the customer service at 844-645-3672 has answered any question I have ever had.
Great device
Great device, definitely works and great customer service from the EXCITEOSA team.
Good results
Device is simple to use, instructions are very user-friendly, customer service is accessible and responsive. Takes some getting used to the tongue zaps, but the treatment period is quick (20 mins/day) and easy to fit into my morning routine; the quality of my sleep has improved significantly. Well worth it! My doc recommended I continue near-daily use (vs 2-3x/wk) after the initial treatment period, so it is just rolled into my routine and way less intrusive than that horrid CPAP!
Incredible device!!!!
I have been using the excite OSA device for over 18 months now. The initial six week period was extremely easy to complete and the before/after results were astonishing. Following the initial six weeks my doctor had me use 2-3 days per week and after 18 months my sleep apnea has no affect what so ever with my level of sleep. Great device strongly recommend its use.

Finished the 60 days and now on 2 times a week. I’m still having symptoms and waking up at least once a night. Using the device isn’t bad. It barely hurts. I’m now on an extension because I need more time to see results. Customer service has been good. I hope it works because I didn’t like the CPAP and don’t want surgery.
i’ve been using the excite device sleep better/feel great for…
i’ve been using the excite device for approximately two years and have gone from moderate apnea to mild. ive maintained mild apnea for about a year and a half and have never slept better. highly recommended.
one more thing : excite’s customer service is outstanding. always available and responsive.
