Looks good at night, but the daytime…
Maybe I didn’t adjust the brightness well enough, but this reflects off of the front windshield. It works great at night and isn’t intrusive. However, when reflecting against the clear, bright sky, I couldn’t see the data that was reflected.Customer service was very responsive and nice.

threw it in trash 20 mins after I opened it
This thing is garbage. went to test it and was going about 20-30 and it was 9-10 mph off

Nice smaller HUD…
Seems to be well made and is reasonably priced…A few notes…1. Adjust the speed control to 102 as the manual says… this seems to be the most accurate setting.When compared to a GPS speed app on a cell phone it was spot on accurate.2. The performance speed bar is rather silly (aka stupid).. always green…must have to go over 100mphto turn red.3. Overspeed alarm factory set at 120mph…really?… you’ll want to reset that.4. The automatic dimming/brightness is very smooth and nice..be sure to go into settings and set it to “0”.5. Did not use the projection film on the windshield…display on glass was bright and clear.6. Compass is nice although a bit small..also set for the travel distance. Nice you can choose from otheroptions.7. Keep in mind this is GPS driven…if you go through long tunnels you may not get response. I’vedriven through short ones and is ok.Overall seems to be nice product and would recommend.Additional notes:Don’t forget to remove the clear plastic protector film from the face of the unit beforeyou use it..Folks!!! this (unfortunately) is not a “plug and play ” unit”…it must be calibrated and preferences set by the user!! Please read the user manual that comeswith it.I suspect the other buyers who gave it a low rating or threw it away didn’t bother to calibrate/set it.

Great HUD – worth the price
this has easy install – just plug it in. just takes a minute to pick up the satellites. The speed matches the speedometer & the waze app, so i think it’s good. Probably one of the best purchases i’ve made for these auto type gadgets. keeps your speed (and the current time) in easy view and your don’t have to drop your eyes down.. definitely a 5 star item for me.

It’s alright
The speedometer reading is smaller than pictured. Daylight savings time occur and the time is still wrong after trying everything. The adapter for the cigarette outlet is oddly shaped. Debating on returning it. It is 3 to 4 mph different than my cruise control

At first I was not happy with it because it was reading 5 kms out at 80 km you were at 85 but once I played around with it now reads true and accurate I like them for the price I bought to one for my personal vehicle and for my work unit I think they do very well for the price and what there suppose to do only thing is not happy with the auto plug choice kind of to short would prefer a longer plug but otherwise no other complaints

When I drive the speed doesn’t go up it’s just stuck at 0 kmh

when this thing can pick up a satellite signal it works great, the issue is a lot of the times it just straight up won’t pick up anything for 10-20 minutes of driving, then it’s very inaccurate and slow when it actually gets a satellite signal, i found a simple fix for this though, simply take off the black sticker part of the front display, solder on a long copper wire (approx 6ft long) to the small antenna you’ll see after taking off the sticker (small circular cutout bottom left) then melt a channel in the plastic for the wire to exit and sit flush with the rest of the plastic so the front sticker will stay flat when reapplied, i simply used a singular 22AWG speaker wire with thin insulation but any small wire with thin insulation will work, then find a place you can loop the extra wire, i took off the cover piece on my A pillar and put it behind there but every vehicle will be different, now with this modification it picks up a satellite signal in under 30 seconds consistently and is much faster and more accurate then before, even works when the vehicle is parked in my carport with a metal roof now, in my opinion the manufacturer should add a standard jack for an external antenna to this since it obviously needs it, hope this diy helps someone with the same issue

The manual is not great but you must re-read it several times. You can always set it back to the default setting in case you make a mistake fine-tuning the product. Show up well using the window film they supply.
