5.5" Universal HUD Head Up Display MPH/KMH GPS Digital Speedometer Over Speed Alarm Tired Driving Warning Windshield Project for All Vehicle Bicycle Motorcycle

very pleased

After 4 months it has stopped working. Not happy.

Camaro speedometer doesn't work anymore. Bought this to use until I get it fixed. 1st off, it's plenty big. The numbers are huge on the screen. Making it very easy to see. It displays other stuff that I'm not interested in. Would have been nice if it displayed the time. But not a big deal. It works excellent. I've tested with my phones GPS as well as those speed trap things that tells you your speed when you drive by. It's spot on. The only thing is that it might take up to 5 minutes to connect to the GPS before it starts telling you the speed. So I have to start the car before I go. Fortunately for me, the lighter socket doesn't shut off when you take the key out on this car. So I just keep it plugged in until I am done driving for the day. If I had to wait for the GPS to connect every time I started the car, it would drive me crazy. Sometimes I use an app on my phone for speedometer while I wait for this to connect. My phone will connect within seconds. So I know it's not the GPS signal. In any case, when it does connect after a minute or 5, it's plenty bright. Numbers huge. Easy to see & works wonderful.

just wanted a speedo for my utility carts. don’t care about the bells and whistles. THIS IS the easiest way to go . i don’t have to run cables, or wires, or mount speed sensors.

Biggest feature I bought this for doesn't exist. Description says "Local time display with auto timezone adjustment". Not only can it not auto switch when crossing into new Time Zones yiy must manually set it. Controls are cheap and clunky. Not that you would expect much better at this price point but be prepared to push buttons multiple times to enter one small change. It either doesn't go to menu you want after a single push or it goes three menus beyond.Display is nice and (oddly) I like the feature to keep you awake. It has three short tones every hour you drive That is if you leave that feature enabled. Found it odd that I had to adjust the speed limit it was reading. Never used the Over Speed alarm so I can't comment on it. Speed limit alarm is only stable at one speed.Had to do over I wouldn't buy again only because the main feature I bought it for doesn't work as advertised.

Easy to use

I was happy with how fast it acquired the speed and the gps. I think it’s a good product, but I did send it back because the green lights were hard to see in the daylight. While it wasn’t for me, it worked well.

never got to see it work when i plugged it in it started to smoke bought a 2nd one that did work 4 star instead of 5 star because it's a little slow tell the speed when accelerating
