Speed Display Radar Traffic Sign, 20"x27"/24"x35" Solar Speed Radar Feedback Sign Road Safety Speed Limit Detector with Accessories, White(50 * 70cm)

Easy to install and works well. There is one design flaw that can be overcome. The overspeed limit takes values in Kilometers even though the sign is set up do Miles per hour. To trick the unit to work you must calculate how many Kilometers are in the desired Miles (MPH) that you want. Take that number and round it up to the next whole number. Enter that number into the Overspeed value and save it and it should work. For example, if you want it set to change colors at 35mph, you must set it to 57 and it will work properly.

They work very well. We have been using two signs for over 6 months with no issues. Also when I sent an inquiry to the manufacturer they responded right away

Bought this for our HOA. Arrived in two packages (in separate deliveries). Build quality isn't great. Metal shavings loose in the enclosure which the exposed PCB probably won't like. One of the screws holding he illuminated display to the front housing was misplaced, causing the PCB to be bent/gapping from the housing. The remaining screws look like they were attampted at least a couple of times each and different screws were used, some of which were too long, and therefore not driven fully home. Lastly, the latches on the enclosure are lockable, but no keys were provided. I haven't mounted it yet, so not sure if it's actually going to work... we'll see.

Excellent service!!! Excellent product!!! Timely responses and very helpful! Thank you much!!

This solar-powered radar speed sign is fantastic! We purchased the 50x70cm (approx 20"x27") white version for our neighborhood street, and it has made a noticeable difference. Drivers consistently slow down when they see their speed displayed. The build quality is sturdy and it looks very professional. Setup was straightforward with the included accessories. The best part is that it's completely solar-powered, so we didn't have to worry about running wires or electricity costs. It works perfectly day and night. It's an excellent tool for promoting road safety and encouraging drivers to obey the speed limit. Highly recommended for communities, schools, or any area with speeding issues! Great value for money.
