Which is better for a first-time mouthpiece user?

The ZQuiet. It needs no boiling, molding or screw setting, so you can wear it the first night. The Snoreguard requires you to adjust the side screws to find a comfortable jaw position.

Is the Snoreguard worth the extra $5.05?

Yes if you want to control how far your jaw moves forward. The screws let you increase advancement gradually. If you would rather not fiddle with settings, the ZQuiet at $39.95 is the simpler buy.

Which has better ratings?

The Snoreguard rates higher at 4.8 versus 4.6, but from 318 ratings against 1,368 for the ZQuiet. The ZQuiet's score rests on far more buyers.

Which is more comfortable to wear all night?

The ZQuiet's open front channel and living hinge let your jaw move naturally, which many users find less restrictive. The Snoreguard holds the jaw forward with screws, which some wearers notice more. Expect mild soreness with either for the first couple of weeks.

Do either need molding or boiling?

No. The ZQuiet is ready to use out of the box. The Snoreguard is also a pre-formed device; you adjust the screws rather than mold the trays.

Neither maker states a replacement interval. Both use medical-grade materials, and the ZQuiet's one-piece hinge design has fewer parts to wear. Plan to replace either if it cracks or stops holding your jaw position.
