MR CARTOOLM60 Car Inclinmeter Level Tilt Meter, Digital HUD GPS Speed Slope Meter, Real-timie Speed, Vehicle tilt/Pitch Angle, Battery Voltage with HD LCD Display for Off-Road Vehicle

I didn't need all the features, but wanted the Compass and Altimeter mainly, and they work great!The inclinometer is nice too, but of course you can only really use it when coasting or stopped. It's got a clock that may need adjusting to daylight savings, and the latitude/longitude is fun and possibly useful for some applications.Mainly though I wanted a compass to be visible all the time and got tired of the cheap spherical oil-filled ones. This one works by GPS, and so does the altimeter, which is very helpful in seeing the changes in elevation, because that does help getting the most economical driving when you know how to gently ease or press the accelerator due to the needs of the slope. Also just really cool to know the elevation of different locations.It's nicely packaged and has a little manual, but you do have to figure out some of it yourself from the hints in the manual. One good thing to know is that changing from Km/hr to MPH in unit settings also automatically changes the elevation from meters to feet.The screen visibility is great both night and day. So far so good! If it lasts many many years I'll have to rate it 6 stars!

Works well has some adjustment within overall happy

I bought this for the GPS speedometer. Unfortunately, the speedometer (checking against other GPS readings and highway mileage posts) is not accurate, and the correction feature provides only a fixed delta so that it cannot account for a percentage error.Still, it is close enough to be useful, the compass is accurate, and the inclinometer makes me smile every time that I check it.

looks great, has dim feature for night, love the simplicity of control and adjustments, the adhesive lasted 2weeks before it came off which I expected. I used JB weld to secure it to top of dash and it looks awesome. It is very accurate and had not given any issues. I would definitely purchase again.

This item is ok and works as expected. I like that the guage shows 1 degree increments, however I think the update interval is way too fast. This causes the reading to bounce between numbers a little too much. I wish this could be a setting the user could change. Other than that the reading is accurate enough, though sometimes it differs from another device I use to check this one.
