Overall sentiment: positive
Customer reviews:
It works very good. If you have problems with installation, watch the YouTube video, it's very helpful. I'm use to huds from GM not aftermarket. The only complaint I have is during the bright sunlight. Other then that it works very good 
 Very Cool!!! 
 Excellent HUD. 
 This was a gift 
 This product is a great OBD2 live heads up display! It has a variety of different sensors and features which are all very tuneable to make sure they are just right for your car. Every single setting on here is 100% changeable which is absolutely great! One of my favorite sensors is the shift light/alarm which can be very helpful in a modified car or can be used by anyone who has a faulty meter on there dash. It can even clear engine codes! This product does everything that a normal Obd2 scanner does with torque pro without having to use your phone. Definitely something you don't see everyday and is definitely a attention grabber. Pro: Extremely Tunable, Plug and Play, Variety of sensors, Bright and Auto Adjusts, Metric and US Standard, Good Build Quality Con: Difficult to get reflection perfect, RPM does lag just a little, Not wireless, Refresh rate a little slow, Adjusting can be hard to figure out, Fuel Consumption in L/H not MPG *Quick tip, if you find your reflector is getting dirty on the adhesive because you messed with it, just use some packaging tape and stick it to the reflector side and pull it off to get any dirt or dust out of the reflector* 
 Looks great. 
 Still love this one overall. It just makes the car look that much more high tech :)

Do have a suggestion tho, (after installing 4 of these in 4 different vehicles) Can u'all make the reflective film bigger? 
 Excelente 
 Works great, it is easy to calibrate. I would give it 5 stars if the fuel consumption was displayed in gallons instead of liters. 
 I really like this product. I like having a HUD with essential info displayed for quick viewing!
The speed has adjustable percentages for different vehicles and I've tuned mine to my vehicle. The default setting was very close. The instructions are in technical verbiage, easy for a technical person to understand, but may be challenging for the average person.
I have my review a 4 star because I enjoy this product. What I do not like is that the display can get washed out in the 12 o'clock sun and in Colorado, it happens quit a bit. The speed does have segmented LEDs which does help, but it does get washed out. On the opposite end of that, the low light setting at night may still be a bit brighter than I would like. Other than that, I would get one of these because it keeps your eyes forward and the info in front of you. 
 I bought this thinking I would return it. I am a driver and frankly, LOVE this HUD! Install is easy, setup was as well. Take your time, read the directions and have fun. 
 Very difficult to program, but works well and looks cool.
