Very easy to install.
Large, brite read out. Very easy to install. I read some reviews that the speed didn't match the speed odometer. If you buy this unit, be sure to download an owners manual from online. It is model A8. Then you can calibrate the speed and RPMs to your car or truck. Also explains how to operate it.

Good product, but warranty response is a ZERO!
Very good product performance, but it completely failed after a year and three months. It continuously resets as if it is just powering on. Seller ignored my messages until I reported that to Amazon. After more messages, seller offered a 20% credit. A 2-year warranty implies replacement, not pro-rated adjustment, like tires are. Seller continues to ignore my messages, and although I've reported this to Amazon repeatedly, I haven't received a warranty replacement of the item. Just so you know what to expect if you have problems . . . .

Compré este display especialmente por la información de temperatura del motor. Hay veces que me distraigo del millero, pero con esto resuelvo definitivamente mi preocupación. Valoró el artículo desde su presentación. Bien empacado, bien organizado, se ve bien. Ofrece muchísima información y va directamente conectado del OBD. Creo que el precio es un poco exagerado en comparación con otros en el mercado, pero este definitivamente ofrece toda la info que necesitas del millero. Puedes elegir qué informaciones poner. Yo particularmente dejé solamente la velocidad y la temperatura

NOT great value
It does technically work, but this has issues. The cost is low however, so I can't be too hard on it. First the angle of my windshield made the squareness of the sticker and device not align. I also could still see double images from screen reflecting off both the inside and outside surface of the glass which made it hard to read and blurry. Bright enough at night, no so during the day. Needs to be brighter. Also, on a plug in hybrid, the device only works when the ICE motor is running. BOOO. Would not buy again.

Love it!
I don't see what's not to like, other than the fuel efficiency, reading and leaders per hour or liters per 100 km, this is a great item, wish I would've purchased this year ago. I don't understand what all the bad reviews are about, but this works 100% for me so far, if that changes in the future, I will come back and revisit this review however, for now, this is a perfectly visible, crystal clear image on my windshield and everything works as it should! Definite buy

This device does not function properly after 6-9 months. Do not buy.
I live in a district with several speed cams and use this HUD to remain conscience of my driving speed at all times. The HUD display relects in my line of sight with out obstructing my vision because of its transparency. The problem is that it stopped functioning properly and does not calibrate only displaying HUD. If someone from the manufactor reads this please contact me.

Received on time. The quality is great. Installation was a breeze. It would really help if they can put it clearly which side of film goes on which side on the windshield. The brightness during the day is amazing. However its ultra bright during night time. I am using it on 2013 Lexus LX570. I have to turn it off during night time. I thought it had an auto feature where it dims when its dark out. Other then that its a great product. Oh yes, the kms are not 100% accurate. It shows speed 5km faster then the car is actually going.

Pro: Bright and clear without even during bright sunlight. I didn’t have to use the sticky film for the windshield. Cons: Speedometer not accurate about 6KM off. Doesn’t display fuel rating, rpm also hit and miss. It’s bulky on my 2023 VW GTI since there aren’t any cutout or slope to hide it like in Mazda 3 GT it’s sits on top of the dash doesn’t look that good. Wish if its little thinner. No height adjustment of the display so it’s sits very close to windshield. I wouldn’t recommend this HUD for newer VW GTI.
