APSX D2 Digital Wideband O2 Air Fuel Ratio Controller All-in-One 2 1/16" (52mm) Gauge (WHITE)

At first look it was a good product but after getting a Ase tech to install the sensor and gauge both stoped working. There was less then 500 miles on the wideband and after trying to resolve the problem with the company and getting no response and the one email I did get was ignorant and completely unprofessional terrible parts and even worse customer service

This was really simple to install and so far is working nicely in my truck. I'm really impressed with the price and seems to be of good quality. And, the seller shipped it fast! So far, I'm very happy!!!

What a great display! Works like a charm. Much better than the other brand that starts with an a and ends with an m. Couldn't be happier

It worked great for about a whole month then nothing and my last review didn't make the cut because my foul language would've made Samuel Jackson proud.

Worst buy I've had on Amazon! Item doesn't work just displays "A0" and nothing else. Try to contact APSX's customer service and no response. No phone number to call them, can only email. I could over look how cheesy and cheap the gauge is, if it worked. Will be returning and buying AEM gauge. The low price isn't worth it!!

I wonder if the seller will refund me under warranty. Going to be spending more money on something that I don't have to worry about going out in another year.

It was easy to hook up . worked well . but after a year it failed . contacted APSX and they were not helpful at all . Got two emails from them . then nothing . My advise to anyone who is looking for a wideband 02 . spend little more on a better quality one that is a well known brand ...

Made very cheap. The wiring harness is very short. My plug connect for the oxygen sensor came in damaged. And also the gauge goes in and out. Will be contacting seller to get a new one.
