A fine device at a reasonable price
I bought the VJOYCAR C60 several weeks ago and am using it in a 2019 vehicle that has a digital Km/h display but not mph. I wanted digital mph also. The GPS speedometer works perfectly. Everything advertised about the unit is true. Set up is no more complex than connecting to USB power. It takes perhaps half a mile to lock onto a satellite and do its housekeeping before speed is displayed. Out of the box it was within +/- 1 to 2 mph. I did choose to recalibrate the speed slightly. This achieved by pressing and holding the up arrow and enter buttons at the same time. I found that pressing the up arrow just slightly prior to pressing the enter button got me into the calibration subroutine every time. Another nice feature is upon stopping, such as a traffic signal, the trip mileage followed shortly by trip time in minutes are displayed. Stop signs tend not to be long enough for this feature to activate. Mileage and time are displayed in whole numbers (no decimals), so the longer the trip, the better the data. Now, there are what appear to be a number of similar devices out there brand labeled by each reseller. The nice thing about the VJOYCAR reseller is that he contacted me personally after my purchase to deal with any issues. I had not noticed that the unit requires a wired USB connection for power, so he kindly supplied a 12 volt adapter so I did not have to sacrifice my USB connector normally used for phone and music. All in all I am happy with the device. The true test will be our Midwest winter temperatures, but for now I'd buy it again.

Does what it needs to with little fuss.
Only annoyance is setting it to MPH is a bit finicky but thats what instruction are for, It is accurate in all my uses, my speedometer just doesnt work during the winter and I got too use to reading from this its rather nifty. For some odd reason it doesn't like some numbers (62 and a few others) and just refuses to display them it just oscillates between the numbers (flickering from 61<->63) it's a nonissue but an oddity.

Good for the Price
Good for the price, I got this as a cheap fix for not having a speedometer at all on my boat. In speed display only mode it is bright enough to read in sunlight. With the entire display on I can barely read speed and can't read anything else. I ended up buying a small flat power bank and mounted that behind the dash just for this. Pros: - It gets the job done and is better than using a phone for speed. - Is readable in sunlight - Has a flat back so you can sticky tape it or velcro it to your dash. - You can calibrate it, in case the speed is incorrect (which it was compared to my car & phone). - While I haven’t gotten it “wet” it has so far not had any issues with light spray and a little moisture. Two complaints, 1) It is USB powered only, which means you either need a power bank or separate voltage converter to power it from 12v. I would have rather this just been 12v direct. Plus having a micro usb port coming out the side makes for an awkward cable situation, hard to install cleanly. 2) It isn't the fastest to update, probably once a second, and you need multiple readings to get a reliable speed. So if you are accelerating you need to be patient about seeing just how fast you are really going. If I still had my old car that didn’t have a working speedo, this would be my go-to quick fix on that as well. Long term there are GPS dial speedos that look and perform much better, and I will get one of those for my boat, but they are 10 times the price. If you are powering this via a power bank keep in mind the power usage is very low... so low most power banks will auto-shutoff to prevent storage power leakage. This was quite frustrating but once I found a cheap power bank that worked I didn’t have to charge it even after hours of use.

You Won't Find Better At This Price
I am very happy with this purchase! Here's what you can expect: The unit comes with a small mount and some 3M tape, which can be applied to the mount or directly to the unit itself. I added some Velcro to mine. After you plug it in, it will take a minute to find the satellites. As others have mentioned, you will probably need to calibrate it. This is easily done with the help of a passenger. I recommend calibration at 70mph+ (when safe and legal to do so of course) for best results. You only need to do this once, after which the unit will display your speed with a high degree of accuracy. The unit is fairly responsive. Not the instant response of a stock speedometer of course, but still pretty good. For a GPS receiver I was impressed. Perfectly acceptable for everyday driving. The display itself is large and easy to read. The manufacturer really dialed in the brightness perfectly. I drive a convertible and can still read the numbers even in direct sunlight. At night, the unit is bright - but not too bright, although it is close. Any brighter and it would be distracting; any dimmer and it would be hard to read during the day. Again I was impressed. If you're looking for an accurate, responsive, easy to read speedometer, you won't find a better one at this price. An excellent value for the money; you really can't go wrong. I wholeheartedly recommend this item.

Works great but...
When I was first getting setup I couldn't figure out why is kept shutting off. It turns out the power plug in is loose and only makes a good connection at certain angles, but I was able to use some blue tac to hold it in place. Other than that, works great!

Simple and effective - golf cart application.
Only been using this for a couple of weeks, but it works great. I installed a USB port in our golf cart and plugged it in, and it worked immediately. The holder lets the speedometer click in place, and can be easily removed. It does fit a little loose, but overall great value for the price. We are getting our golf cart approved as an LSV so we can drive on the streets of our town, and a speedometer is required.

Not accurate and slow to respond, showing at least 5-8 kms below actual speed when tested against phone GPS and car speed.

I really like this product. Is bright and has lots of functions. Sits really well on my dashboard. It’s cheap & cheerful, but I find around town it takes an age to update the speed. I do some motorway driving and it works well when the speed doesn’t change that quickly. Would be 5 stars if It was quickly to update. Came from the USA well before the ETA

El artículo es pequeño y solo necesita conectarse al encendedor por usb, está en Millas pero aún así es fácil entender la velocidad a la que marca, en túneles no agarra pero fuera de eso es un artículo que recomiendo comprar
