Basic functionality, takes a little to figure out, but did what I needed
I just needed to check the error codes on my 2014 F150 and clear them. I did this once for free at AutoZone, but the codes came back and I needed to verify a repair I made. This unit was inexpensive - making it cheaper and more convenient than running back and forth to the auto parts store. The instructions are a bit lacking, but there are only a few options and buttons, so it shouldn't take too much to figure it out, My issue was that the codes are easily read on one screen, but you need to go to a different screen to clear them. Not hard, just not intuitive. If you just want the codes (and maybe clear them) so that you can investigate fixes (or just let you know if you should go straight to your mechanic), this should work fine. If you want a lot of detailed diagnostic info, you may be better served with a more sophisticated, higher dollar unit. I'm happy with this one.

Works great!
Works perfectly! Used this when trying to get my vehicle ready to pass emissions. Worth the money spent to avoid the headache at the emissions place.

To ‘techy’ for most…
While this seems very impressive, even with the manual, trying to use this became very confusing for me, an, ‘average Joe’.

Easy to use
Needed something just to check codes in an event where I couldn’t get to a mechanic. Gives a peace of mind when you can check for yourself. Great price, easy to use.

Great OBD2 Scanner with Battery Tester – Highly Recommend!
I’m impressed with the OBD2 Scanner with Battery Tester Enhanced FIXD Car Diagnostic Tool! It’s easy to use, connects quickly to the OBD II port, and shows error codes, battery health, and more. The large, clear display is user-friendly, and it works on both my car and truck. The ability to clear engine codes and reset the check engine light has saved me time and money. Compact and portable, this tool is a must-have for anyone wanting to take control of their vehicle’s diagnostics.

As much as I like my Bluetooth OBD2 Scanners - I like having a separate tool.
As the headline states: As much as I like my Bluetooth OBD2 Scanners - I like having a separate tool. I own a number of Bluetooth OBD2 Scanners on my iPhone. All work well but I like the simplicity of a standalone device. One of the biggest issues I have with Bluetooth OBD2 software is usually the interface is overly designed and not very intuitive. It can take forever to find your way around the software. Enter this OBD2 Scanner with Battery Tester. Simple to use, everything is at your fingertips. The two nicest features are the Battery Tester and measuring the alternator current. I have 2003 pickup with a 5 year old battery and the original alternator. It's nice being able to monitor both for a peace of mind. The scanner has so many other features that for the price it's an amazing deal.

Very good product. Buy it.
I was a bit under whelmed based off of the reviews. but it does do what you need it to at an EXTREME affordable price. the GUI is vary basic but in color! I don't think it has live data. BUY IT but don't think you are going to tune your F1 with it.
