One ticket costs more than five McFlash units
A single speeding citation in most states runs $150–$400 before court fees, and the insurance surcharge that follows typically lasts three years. McFlash gives you the seconds of warning that turn a citation into a glance at your speedometer.
Earlier warning
Long-range front and rear antennas pick up Ka-band before you are inside the officer's targeting window.
Fewer false alarms
City mode filters the automatic doors and blind-spot radar that make cheap detectors cry wolf.
No install bill
Suction mount and 12V plug. Move it between vehicles in seconds — no shop, no wiring harness.
Fitted in two minutes, no tools
There is nothing to wire and nothing to configure. Three steps between opening the box and your first alert.
- 01
Mount it
Press the suction bracket onto the windshield or drop the unit on the dash pad. No drilling, no trim removal, no shop visit.
- 02
Plug it in
One cable into the 12V socket. McFlash powers up, self-tests the antennas and is scanning before you leave the driveway.
- 03
Drive
Pick City or Highway once. From then on you get a spoken band callout and signal bars the moment radar or laser touches the car.

What drivers say after a month
Feedback from owners across the US, UK, Canada, Australia and New Zealand.
“Picked up Ka-band about half a mile before the cruiser was even visible over the rise. That is the whole reason I bought it.”
Marcus D.Verified buyer
Dallas, TX · F-150
“City mode was the difference for me. My old detector screamed at every supermarket door — this one stays quiet until it matters.”
Ellie R.Verified buyer
Manchester, UK · Golf GTI
“Two minutes on the windshield, plugged into the 12V and done. I move it between the wagon and the work van without thinking about it.”
Dave K.Verified buyer
Brisbane, AU · HiLux
“Ordered two, one for each car. Shipping was quicker than expected and the voice alerts are clear enough to hear over the stereo.”
Priya S.Verified buyer
Toronto, ON · CR-V
“I commute 120 miles a day. It has already flagged three speed traps I would have walked straight into on autopilot.”
Tom B.Verified buyer
Phoenix, AZ · Model 3
“Cheaper than one ticket and it does what the £300 units at the shop claim to do. No regrets after four months.”
Jamie O.Verified buyer

United States
Before you order: check your state
Radar detectors are legal for privately-owned passenger vehicles in 48 states. They are prohibited in Virginia and Washington, D.C., and in commercial vehicles over 10,000 lbs anywhere in the US. A handful of states restrict windshield-mounted objects, so we ship a dashboard-friendly mount.

Rules where you drive
We ship worldwide, but detector law is national. Read your country before ordering — it takes a minute and it is your responsibility as the importer.

Frequently asked questions
Is McFlash legal in my state?
Radar detectors are legal in privately-owned passenger vehicles in every US state except Virginia and Washington, D.C. They are prohibited in commercial vehicles over 10,000 lbs under federal rules. Check our state-by-state legality guide before ordering.
What does McFlash detect?
X, K, Ka and Ku radar bands, laser (LiDAR) guns and VG-2 detection, from all 360 degrees around the vehicle.
How long does installation take?
Under two minutes. Attach the suction mount to the windshield or dashboard and plug the cable into the 12V socket. No wiring or tools.
How much is shipping?
Shipping is free worldwide on every order, and we ship to 40+ countries. Your delivery estimate is shown at checkout.
Are radar detectors legal outside the US?
They are legal in the UK and New Zealand, restricted in Ireland, prohibited in most Australian states and in several Canadian provinces. Read the country guide for your location before ordering — as the importer, compliance is your responsibility.
Does McFlash catch instant-on radar?
Yes. The Ka-band antenna picks up instant-on and pulsed radar the moment the gun keys up, including hits aimed at vehicles ahead of you, which is usually your earliest warning.
Does it detect speed cameras?
McFlash alerts on radar-based and laser-based camera systems, including many mobile speed vans. Purely optical or average-speed camera systems emit no signal, so no detector can see them.
What if it does not work for me?
Return it within 30 days of delivery for a refund of the product price under our money-back guarantee. See the warranty page for full terms.
