Excellent
Great product, works great with my HP tuner. Easy install but I do have a lift. Took me about an hour because I ran the wiring the right way for a permanent install.

Wideband UEGO AFR
Reads the AFR pretty well and accurate. It is truth worthy and will have your tune on point. Also, gives the interior a more aggressive feel.

Works as it should, no issues. Simple install, either weld in your own bung or have a shop install pending skill set. Accurate reading for tuning and engine monitoring.

X-Series Wideband
The AEM X-Series Wideband UEGO AFR Gauge is a reliable and accurate tool for monitoring your air-fuel ratio (AFR). It uses the Bosch LSU 4.9 sensor, which is known for its accuracy and fast response. This is especially helpful when tuning your engine or keeping an eye on your AFR for performance and safety.

Easy
It was my first time and I had no issues. YouTube was helpful. Not all wires were used.

Excellent wideband, and integrates well with most tuners
This is not the only wideband sensor I have or have used, but it's probably my current favorite for everyday tuning and monitoring of A/F ratio. The 30-0334 is another $50, but can be wired to your car's electronics simply by plugging it's jumper OBD2 connector onto your vehicle's and can directly broadcast your data over the car's CAN Bus. The 30-0300 is the identical sensor and gauge, save for the OBD2 connector part. All wires on that version need to be manually connected to your vehicle, but it also has the capability of being used over CAN or providing an output for data logging, tuning etc.. If you have an older carbureted and/or non OBD2 vehicle, don't spend the extra $50 on the 0334. Mine is being used on a 2017 C7 Corvette, and has been an indispensable tool in conjunction with my HP Tuners to get my combination dialed in. My installation took longer than most, as I pulled my radio out to incorporate it in the storage area behind the display screen. Most standard installs probably take about an hour. The response time and resolution are great on this sensor, and unlike a competitor's gauge/sensor that I have on a Mustang, this one consistently fires up every time and reads without having to reboot/key cycle occasionally like the other brand's does. It integrates well with HP Tuners. (There's a ton of info on the net on how to set it up with HP) I have absolutely nothing bad to say about this one. I realize they aren't cheap, but I can honestly say based on its performance and reliability combined with how well it provides a necessary function for tuning, it's worth every penny! Great tool.

Aem afr gauge
This is as good as expected or better. Such a good fast accurate reading for tuning now with the Uego sensor kit. Very satisfied.
