ONNAIS Open-Design Biometric Pistol Safe Review: Worth It?
The ONNAIS Open-Design Biometric Pistol Safe takes a different approach from a typical lidded lock box. There is no lid to lift: the seller describes an open-access design that unlocks with a fingerprint in about half a second and is meant for bedside, wall, desk and vehicle mounting. It is a small, hard-mounted unit that suits someone who wants to fix one handgun’s storage in place and reach it quickly. If you want a safe with a full enclosure, room for extras or a published fire rating, it may not suit you. This review is based on the Amazon listing, the seller’s bullets and general safe-storage knowledge, not on owning or handling the product.
Bottom line:
- Best fit: a compact, screw-mounted pistol holder with fingerprint, keypad and key access, a rechargeable battery and a charging cable.
- Main trade-offs: the open design offers less enclosure than a lidded box, no interior capacity is given in the specs, and no owner feedback summary was available.
- Price: it sat in the under $100 range when we wrote this, so check the current price.

The listing does not publish an interior volume or a steel gauge, and there is no fire or burglary rating. The seller does state that the product is backed by a lifetime warranty, but warranty terms vary, so read the actual terms on the listing or in the manual before relying on that.
Access and lock
The star feature is speed. The seller says the fingerprint reader unlocks in 0.5 seconds with an open-access design, so there is no lid to lift and no key to fumble. That is a manufacturer claim, so judge it by what owners say about reliability. The unit can store up to 80 fingerprints, which is more than any household needs, but the spare slots let you enroll the same finger several times, a common way to improve recognition.
Backups matter more with an open design that sits ready on a surface. The listing says there is a keypad and a mechanical key, so you have three routes in. A keypad is useful if your fingers are wet or dirty, while the key covers a drained battery. Because this unit is meant to hold a handgun in a fixed spot, think carefully about who in your home can reach the keypad, and pick a code that cannot be guessed. Keep the mechanical key somewhere other than next to the safe.
The seller also mentions a reinforced latch and a built-in trigger lock. The listing does not explain how these work, so look for photos or the manual to understand how your handgun sits and what the trigger lock does before you rely on it.
Build and security features
The body is listed as alloy steel with a scratch-resistant finish. No gauge is given, so there is no honest way to compare wall thickness with other boxes. The seller calls the unit tamper-resistant and childproof. Remember what an open-design unit is: a quick-access holder that restricts who can retrieve the handgun, mounted so it cannot be walked off with. It does not wrap the firearm in a sealed steel box, so it relies on its latch, its trigger lock and its mounting.
That makes installation the key security factor. The listing says pre-drilled holes and eight mounting screws are included for permanent installation in vehicles, nightstands or cabinets. Fasten it to something solid, such as a structural frame or a thick panel, not thin plywood or trim. A well-mounted unit is hard to pull off, while a loosely fixed one is barely more secure than leaving the gun on a shelf.
Watch: Athletic Standard published a review of this exact open-design model that shows the unit’s size and how it mounts.
Interior and fit
This is where an honest review has to be careful. The specs give an outside size of 6.5 by 3.5 by 7.9 inches but no interior volume or handgun length limit. The description mentions a handgun fit guide and a console fit guide, which suggests the seller expects buyers to check compatibility. Do the same: find the fit guide in the listing images, then compare it with your handgun’s exact make and model, including any light or optic. A narrow 3.5 inch width suggests a slim holder, so full-size pistols with wide light attachments could be a poor match.
Because it is an open design, there is no space for spare items. Do not expect to stash a wallet, jewelry or a second firearm. If you want a lidded box with foam and room for extras, look at the BILLCONCH Biometric Handgun Safe, which the listing describes as fitting up to two standard handguns.
Mounting and placement
Versatile mounting is the draw. The listing lists wall, desk, undercounter, bedside and nightstand mounts, and the seller also pitches it for center consoles and under-seat spots in SUVs and pickups. The description mentions trunk mounting too. Because the unit is small, it can disappear under a desk edge or inside a cabinet, which is useful in a home with limited space.
Vehicle use brings extra considerations. Rules on firearm storage in vehicles differ widely from state to state, so check yours before relying on a car mount. The same applies to child-access-prevention and storage laws at home. Also remember that a car interior swings through hot and cold extremes, so keep an eye on the battery and the finish.
Power and batteries
Power is a strong point on paper. The seller says the built-in rechargeable battery lasts up to one year on a single charge and fully recharges in two hours, and a charging cable is in the box. A year is a manufacturer figure that depends on how often you use the unit and the temperature, so plan to check the charge periodically instead of waiting for a warning. Charge it on a schedule, such as when you change smoke detector batteries.
The listing does not describe a low-battery alert, so look at the manual or product images to learn how the safe signals a weak charge. With a mechanical key and keypad backup, you are not entirely dependent on the fingerprint reader, but test all three methods after each recharge.
What owners say
No owner feedback summary was available for this model at the time of writing, so we cannot describe common praise or complaints and we will not invent any. When you read the customer reviews and Q&A, check for these points:
- Fingerprint reliability, including cold or dry fingers.
- Which handgun models fit, and whether lights or optics get in the way.
- How secure the latch feels and whether the trigger lock is easy to use.
- Whether the mounting screws and pre-drilled holes work on your surface.
- Real-world battery life compared with the one-year claim.
- How the seller handles warranty claims and replacement keys.

How it compares
The closest rival in price is the RPNB RP311F, a slim vertical lock box with a 500 DPI sensor, a keypad and a key, listed in the same under $100 range. It encloses the firearm in a drawer-style body, which some buyers prefer.
The Hornady RAPiD Safe Night Guard uses RFID tags and a wristband rather than a fingerprint, with a clock, USB ports and 14 gauge steel per the seller. Its price varies, so check it directly.
For a keypad-and-RFID vault that bolts to a surface, the Hornady RAPiD Safe Keypad Vault sits in the $100 to $200 range and lists a 14 gauge body. For a roomier box with app control, see the BILLCONCH review. You can also browse our best gun safes overview or the full gun safe reviews A to Z list.

Final verdict
The ONNAIS Open-Design Biometric Pistol Safe is a niche but sensible choice for someone who wants a handgun held in a fixed, quickly reachable spot at home or in a vehicle, with a fast fingerprint reader, keypad and key backups and a rechargeable battery. The trade-off is clear: it is not a sealed box, details like interior fit are thin in the specs, and without an owner feedback summary we cannot vouch for its long-term performance. Check the fit guide against your handgun, read the warranty terms, anchor the unit properly and test every unlock method on arrival. Storage and child-access laws vary by state, so check yours.
