Reviewers agree that the Kingston DataTraveler Locker+ offers a decent, cheap secure solution for those who don't need government-grade security on their USB flash drive. The DT Locker+ offers 256-bit, hardware-based encryption, protected by a password that you set. After 10 incorrect password entries, it reformats the drive, at which point it becomes usable again (but without your data). You save a hint when you first set the password, which you can request again at any time.
The drive requires two spare drive letters: one that's used for the public installation files, and one that becomes visible when you've unlocked the secure portion of the drive, where your own files go.
Reviewers liked the drive's simple security, its cap design (a swiveling cover means the cap can't get lost) and price. They were less enthusiastic about the low USB 2.0 transfer speeds, common among secure drives. Users at Amazon.com reported conflicts and issues when attempting to install the drive while using a USB hub and while having external card readers of any kind attached to their computers.
Professional reviews of the Kingston DataTraveler Locker+ are posted at sites including Computerworld.com, PCMag.com, CravingTech.com and The-Gadgeteer.com. About 70 users weigh in on Amazon.com.
PC Magazine awards 4 out of 5 stars to the Kingston DataTraveler Locker+, praising its professional-quality 256-bit encryption, low price and swivel cap that can't be lost. Their only con is its lack of Linux compatibility.

Computerworld.com compares the Kingston DataTraveler Locker+ and the earlier Locker (no plus) model. Reviewer Lucas Mearian praises the drive's security, which locks down and reformats after 10 unsuccessful password attempts, a feature that is rare at this price point. He also likes the swivel cap design. He does one transfer of real-world data, finding the results acceptable.

The-Gadgeteer.com reviews the Kingston DataTraveler Locker+ USB flash drive, praising its hardware-based encryption, simple password entry and low price. You do trade off the ability to boot with the drive or use Linux, he notes. The drive's security will wipe the hard drive after 10 incorrect password entries, but at that poinit becomes usable again.

Reviewer Rob Williams tests the speed of the Kingston DataTraveler Locker+ drive using benchmarks and real-world data, finding that the read speed nearly tops out the USB 2.0 connection, while the write speed is respectable for a secure USB flash drive. The device is easy to use once it's been installed, requiring a password but no other special steps. The cons at the time he writes this review are the price (considerably higher than the current estimated price) and its incompatibility with Linux.

Reviewer Tomas Ratas awards a perfect 10-star score to the Kingston DataTraveler Locker+ secure USB flash drive, noting that at launch it was pricey and that it is not Linux compatible, but that any drawbacks are offset by the performance, rugged design, simple security and Windows/MacOS compatibility of the drive.

CravingTech.com reviews the Kingston DataTraveler Locker+ secure USB flash drive, praising its svelte design, swivel cap and installation-free security. Because the drive is always encrypted, giving it to a friend is not possible unless you're willing to share your password, writer Michael Aulia notes.

Cliff Joseph, writing a short review originally posted in MacWorld, praises the drive's security and MacOS compatibility, noting that it adds an icon to the Dock to allow for quick formatting, ejecting and browsing. The price (at the time of this review) is high, he notes, but may be worth it for those seeking security and portability of their files.

Reviewer Kirk Spencer awards the Kingston DataTraveler Locker+ secure USB flash drive a Highly Recommended rating, writing "the drive does exactly what it's marketed for and it does it extremely well." His benchmark speed tests produce average results, which he feels are offset by the drive's security features and ease of use.
