QIUI Little Devil App-Controlled E-Stim BDSM Collar
$148.00 $195.00SAVE 24%
An adjustable silicone e-stim collar with QIUI app control, three play modes, four conductive rivets, a detachable level detector, a physical padlock, and a built-in rechargeable battery.
What You Are Buying
A Collar, App Control, Motion Sensing and a Real Lock
The Little Devil combines the electronic control unit, four conductive rivets and a 6-axis gyroscope in the collar itself. The separate level detector plugs into the Micro-USB port when you want to use the height-based mode.
The physical padlock is separate from the electronics. The lock and matching key are included, so the restraint part does not depend on the phone.

QIUI App
Three Modes, Explained Without the Jargon
Crawling Mode
The attachable level detector lets the controller set a height line. The current product description says stimulation is triggered when the wearer rises above that set height.
Grounding Mode
The built-in motion sensor is used to set a movement range. The product description says stimulation is triggered if movement goes outside that preset range.
Free Play Mode
The controller uses the QIUI app directly to choose stimulation settings and activation. The current page says frequency and voltage can be adjusted in the app.
The written product copy also calls these Climbing, Trapped and Custom modes. The product graphic uses Crawling, Grounding and Free Play, so both naming systems come from the same page.
Crawling Mode Hardware
The Level Detector Is a Separate Part
The small detector included in the box attaches to the collar through the Micro-USB port. The product information graphic lists a distance precision of 1 cm.
If Crawling Mode is the reason you are buying the collar, check that this detector is in the package when it arrives.
The 1 cm figure is a manufacturer-stated specification from the current product graphic.
Grounding Mode Hardware
Built-In 6-Axis Gyroscope
The product graphic identifies an independent CPU chip and a 6-axis gyroscope inside the collar. This is the hardware used for the movement-based mode.
The same graphic claims movement detection with 1 cm precision. That remains a manufacturer-stated figure rather than an independently verified performance claim.

Fit Before You Buy
Measure Your Neck Before Ordering
The current product page contains two fit figures. The written specification says 37–56 cm adjustable. The product information graphic says 37–57 cm / 14.5–22.5 in.
Both figures are kept because the source conflicts. If your measurement sits close to either end of the range, allow room for normal breathing and movement instead of treating the maximum figure as a target fit.

Battery & Charging
No Replaceable Battery to Buy
The rechargeable battery is built into the collar. Charging uses the Micro-USB port and the charging cable supplied in the box.
The product graphic specifically says <200 mA is charging current, not stimulation current.
Materials & Contact Points
Silicone Strap, Bronze-Alloy Conductive Rivets
The current page lists silicone for the collar surface, bronze alloy for the electrical conductive rivets, and ABS polymer plus bioplastic for other components and accessories.
The product graphic shows four metallic conductive rivets and states output up to 10 mA. That figure is kept as a manufacturer-stated specification, not as a medical or universal safety guarantee.
The current page does not publish a medical-grade material certification or independent electrical-safety certification for this collar, so none is claimed here.
In the Box
The current product page also states discreet packaging.
Specifications
Collar & Control
Fit, Power & Package
The current page contains two neck-size figures. The written specification says 37–56 cm, while the product graphic says 37–57 cm / 14.5–22.5 in. Both are retained here rather than silently choosing one.
Safe Use & Care
Adults 18+ only. Read the included manual before first use.
FDA guidance for powered muscle stimulators warns against electrical stimulation over the neck because severe throat-muscle spasm and breathing difficulty can occur.
Do not use electrical stimulation with a cardiac demand pacemaker. Seek medical guidance if you have an implanted electronic device.
Stop immediately for pain, burning, dizziness, faintness, breathing difficulty, abnormal heart sensations or visible skin injury.
The current product page does not publish a waterproof rating or cleaning method. Follow the included manual rather than assuming the collar or charging port can be submerged.
The 10 mA output and 1 cm precision figures come from the current product graphics and are not independent safety or performance certifications.

Questions, Answered
What are the three modes?
The product graphic calls them Crawling Mode, Grounding Mode and Free Play Mode. The written copy also uses Climbing, Trapped and Custom. Crawling uses the attachable level detector, Grounding uses movement sensing, and Free Play gives the controller direct app control.
What neck size does it fit?
The current page contains two figures: 37–56 cm in the written specification and 37–57 cm / 14.5–22.5 in in the product information graphic. Both are kept because the source conflicts.
Does the padlock depend on the app?
No. The package includes a separate physical padlock and physical key. The app controls the electronic functions, while the padlock is mechanical.
Can it be controlled from another city or country?
The current product copy markets long-distance play, but the technical information shown on the page only confirms Bluetooth and the QIUI app. It does not publish a Bluetooth range or clearly document the network path used for off-site control, so this page does not promise a specific distance.
How long does the battery last?
The current product page states 4–5 hours of continuous play per full charge. Charging is by Micro-USB at 5V, with charging current listed below 200 mA.
What is included?
One Little Devil shock collar, one attachable level detector, one Micro-USB charging cable, one physical padlock, one physical padlock key and one product manual.
Where do I get the QIUI app?
The current product page tells users to search for "QIUI" in the Apple App Store or Google Play Store.
