SnoreRx Plus and VitalSleep are two of the most popular adjustable mandibular advancement devices (MADs) on the market. Both let you fine-tune how far your lower jaw is held forward, which is the single most important factor in how well a mouthpiece stops snoring. But they take very different approaches to fit, adjustment, and price.
In this 2026 comparison we break down where each device wins so you can pick the right one the first time.
Quick Verdict
- Choose SnoreRx Plus if you want the most precise, calibrated jaw adjustment and a custom, dentist-quality fit.
- Choose VitalSleep if you want a lower price, a lifetime replacement guarantee, and a built-in breathing hole for mouth breathers.
SnoreRx Plus: Best for Precision and Comfort
SnoreRx Plus is a custom boil-and-bite MAD that advances the jaw in precise 1 mm increments (up to about 6 mm) using its "Calibrator" mechanism. Because you can dial the setting in exactly, most people find the sweet spot between snore relief and jaw comfort without over-advancing. Its "Comfort Cushions" cradle the teeth, and there is no metal or springs.

VitalSleep: Best for Value and Mouth Breathers
VitalSleep is an adjustable boil-and-bite MAD that uses a small hex tool ("Accu-Adjust") to move the lower tray forward. It typically costs less than SnoreRx Plus, comes in two sizes (regular and small), includes an air hole so you can breathe through your mouth, and is backed by a lifetime replacement guarantee — a standout in this category.

Which Should You Choose?
If precise, repeatable jaw adjustment and a premium feel matter most, SnoreRx Plus is the stronger pick. If you want to spend less, need to breathe through your mouth, or want the security of a lifetime replacement, VitalSleep is the better value. Both are effective MADs, so the decision usually comes down to budget and whether you are a mouth breather.
Frequently Asked Questions
Is SnoreRx Plus worth the extra money over VitalSleep?
If you value precise calibration and a custom feel, yes. If budget is the priority, VitalSleep delivers most of the benefit for less.
Can I use either device if I breathe through my mouth?
VitalSleep has a dedicated air hole, making it the friendlier choice for mouth breathers. SnoreRx Plus can still work but is less accommodating.
How long do these mouthpieces last?
Most adjustable MADs last 6–12 months with proper care. VitalSleep's lifetime replacement guarantee can offset that cost over time.
