I love this heads up display. I previously had the X5 HUD Arpenkin X5 HUD 3" which I also really liked, but it had too many things going on. For instance, the "red line" on the X5 is arbitrary and didn't match my car's and the RPM gauge would frequently flash when I was idle because it thought my RPMs were too low. All in all, it was a good product that I had for around a year and a half. The other HUDs on the market are even MORE cluttered and grotesque looking. Which is why you should buy this. Also, I am not being paid to write this review and I didn't get it for free. Just trying to help you make the right decision.
So I had the other HUD for like a year and a half. Until I saw this guy. It doesn't say in the product title, but the model number is the A100. The only thing this displays is your speed, and it has a few alarms it can trigger. Watch my video for a more detailed review, but this thing is easy to install and setup and is very clean and elegant. It also came with 4 circular 3M double sided sticky tape that will hold it in place on your dashboard. The instructions are written in Chinese and then poorly translated into English but it's easy to understand what they're trying to tell you. You should buy this if you don't want to have to look down to see your speed constantly and you want something that is minimalistic.
Also, I ordered this on a Tuesday and received it the next day (free shipping for prime members is great!). If you watch my video and you also have to remove your weather stripping it's as easy as giving it a firm tug away from the metal and then putting it back on is as simple as pushing it into place.
