Tachometer Gauge,Geevorks 3.75" 12V Automotive Replacement Tachometers 0-8000 RPM,RPM Tachometer for Car 4/6/8 Cylinder Engines

The media could not be loaded. Great quality easy to install light is bright and functional is a great up grade the fitment is nice with the great colors to read from the gauge.

Purchased this Tach in June, but just now installed it. My 30 day return expired, so I assume i no longer have a warranty. The product is defective and in my opinion I would not recommend it. It worked for a week, and now all it does is buzz and the needle just vibrates. It no longer shows the RPM of the engine. It is now just junk I wasted money on. I would not recommend this product.

I think the reason why most of you are having problems is because you followed the instructions. They are wrong. Black wire goes to ground not “positive”. Mine works fine! I noticed that before installing. If you put the black wire to a 12v positive wire you’re definitely going to have problems lol. It’s cheap. Does the job for my 90’s ride. Works just fine

Initially, this product was received as advertised Unit worked well and the installation was fairly easy.That being said, only time will tell it's true quality.

The media could not be loaded. First off the thing has a mind of its own. Second that clicky weird thing irritates me. Okay, so I noticed when it was all hooked up on start up it does that clicky thing for 10 seconds before it goes to the correct idle rpms. Pretty annoying. So I ran a switch to the signal wire. After it's running I can arm the signal and bypass that initial 10 secs of clicking. Hence the 0 rpms on start up. It works okay in my 91 GMC 5.7. I give it 3 stars

There’s not a casing around it so it sorta up to you how you mount it

To start this off my package came beaten to hell, it was shipped in a plastic bag with nothing to protect it during shipping but it thankfully still turned on when I received it.I installed it the same day and it worked great for the first drive i went on... after that it wasn't working properly. The needle was stuck at 2000 rpm instead of 0 when turned off. I decided it was too much of a hassle to try and get my 20 bucks back so i took it apart to try and get it working again.And from the look of the inside, it's not assembled well whatsoever. You can tell the electronics are soldered by hand, which is ok... if you know how to solder. I'm shocked none of the connections broke when it was knocked around during shipping. It also had random blobs of solder stuck to the board where no connections were, probably just dripped on during the process and they didn't care enough to remove them.I eventually got it to work again, but it's a minor inconvenience. I have to put my vehicle into accessory mode and let the gauge "prime" itself, where the needle goes forward and back until it rests at 0 again, and then I can start my vehicle. If I start it immediately the gauge breaks itself again.It also does this awful buzzing sound when you first turn it on, it's not so bad for me to deal with but could be a deal breaker for others. The instructions it came with said it had a setting where you can change the color of the backlight, after trying many different things I can confirm you cannot change the color.So is it worth the $20 I spent? Yes, you do get what you pay for. Am I going to buy this product again? Probably never

First off the wires are too short to install without adding extensions. Make sure you test it before you clean everything up since mine was broken out of the box just buzzes super loud and vibrates right at 100-200rpm no matter what the engine is doing. Since it’s a 30 minute drive to the drop off to return or an extra $8 this one’s just going into the garbage and I’ll reorder one from a different company that hopefully will work.
