What it does well!

Key strengths users can’t stop talking about.
Saves money on diagnostics
I bought one and I might not use every single future but it saved me literally thousands.
Extensive coverage of vehicle makes
Best scan tool with built-in module programming? I'm looking for something that can program new and existing modules on almost any car.
I’ve heard mixed reviews about Autel, but they do seem to offer extensive coverage.
Comprehensive coverage of vehicle makes and models
I'm super interested to see more about it, and how it compares to some of the popular Amazon bi-directional tools.
Real-time graphing features available
If you want a tablet based (Android) scan tool with bi-directional control, special functions, real time graphing, etc.
Advanced features for specific vehicle diagnostics
Took 4 of them till I found one that would run it and even then it’s sketchy and says it fails but it performs per Subaru service manual.
As you get even more expensive you get into the realms of bi directional where the scanner can perform resets and adaptations of modules.
Cost-effective compared to other scanners
it is cheaper than other scanners and has some functionality I can only get through an upgraded scanner like EPB codes, making key fobs, TPMS, etc...
Good value for mid-range scanning needs
Autel scanners are good if you need a cheap or mid range one.
Recommended for diesel diagnostics
for most diesels a nice Autel will do.
Autels do programming to right?
Good value for money
Autel would be the way to go, your dollar goes further with them.
Comprehensive features for diagnostics
Diverse card templates, QR code sharing & scanning, social media card sharing.
It seems like a very useful app.
Large display improves user experience
Hi. I would like a code.
Good value for advanced features
I would love to give it a try.
Hello /u/Goldengirl_1977! Thank you for posting in r/DataHoarder. Please remember to read our [Ru
Comprehensive diagnostic capabilities
It truly feels like a digital notebook that feels like a paper notebook.
Extensive active tests available
it's been an amazing project now topping my collection over 110K photos.

Where it needs some work!

Areas to watch—feedback on possible improvements.
Full diagnostic tools are not necessary for everyone
I promise you won’t make use of a full diagnostic tool, nor will you find one at an affordable price.
Complexity and cost of programming modules
Getting into programming your own modules is expensive and usually requires subscriptions from the automaker in addition to the hardware.
regular pass thru programming is super complicated and costly.
High cost of full diagnostic tools
Hard to justify spending 1k as a shade tree mechanic but cars these days need 5k dollar scan tools to diagnose a 5 dollar relay.
Damn blast did it take me a while to learn about the forscan dongles on eBay 😁
You're better off getting a cheap tech2 or forscan interface instead of an expensive scanner that still might not have as much functionality.
Complexity of programming modules may deter some users
Even the $400 ones don’t have full access to the vehicle’s programming functions.
Subscription limits certain features
been running it for a year or 2 with an expired subscription and doesn't hinder me at all.
Complexity of full diagnostic tools for some users
I seem to grab the Solus more but I know that scanner won't be cheap.

Core Power Plays

The specs and strengths that make it shine.
Discussion on the necessity of advanced diagnostic tools
Unless i can hit a button the $400 one and it actually fixes the problem, otherwise, i can only imagine it has more codes for complex issues?
By law manufacturers have to make their cars spit out OBD2 codes, but if you read the car with a smart enough scanner then it'll read much more detailed codes.
The Scribe did exactly that for me.
I've been reading up on photo scanners and am having trouble deciding on which one to get/use.
Comparison of features with other tools
I wasn't happy at first, even with the value buying an Autel made me feel "dirty" LOL. It's been a GREAT little tool, earned its keep well and never skipped a beat.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Free code readings available at auto parts stores
Most auto parts stores will read the code for free, hoping to sell you the parts.
Comparison to other affordable code readers
Blue Driver Driver Pro gives good info and live data across gas and diesel engines for about $100+.
Different tools for varying needs
Really considering the new gear wrench 7"tablet scan tool but also possibly an autel.
I'm still learning to navigate the software, but so far I'm fairly impressed.
Buy once, no fees after, best I've found for the money and no fees afterwards.
if this is your living get an autel.
Different needs for scan tools
I’ve heard over and over in countless videos I’ve watched that 'there is no perfect scan tool'.
everyone's got different needs, and it seems like you're looking for something that goes beyond basic code reading.
I needed a scanner that could actually do something, not just read basic codes like BlueDriver.
Costs associated with good diagnostic tools
Good tools are BIG money. I don't think I'd fully trust them.
Comparison of different scan tools and their features
I doubt if HF would come up with a better bang for the buck. Their code readers are way overpriced already.
The D7 hasn't failed me on pulling pins for IMMO work, where the Otofix has.
Comparison to Snap-on tools highlights value perception
Autel maxi sys far outweighs the usefulness of snap on solus and other clones.
Variability in scanners based on specific vehicle needs
What you really want to do is research a scanner specifically for your make of car.
Preference for specific brand software over generic tools
I just use bmws ista software otherwise before that I just had a handle held code reader and that pretty much did the job for me.
I personally use the Foxwell NT510 Elite because that’s what my mom got me for Christmas.
The only issue is the codes are all in German.
Concerns about learning curve and usability of advanced tools
As for scanners, I liked the snap on MODIS back in the day with is built in o-scope.
Comparison of dedicated vs all-in-one scanners
it's better to get a scanner that's dedicated.
They just came out with their wireless module and mobile app unless you prefer a laptop.
I think that's the cheaper way to go than getting one scanner that does it all.
Comparisons to other diagnostic tools
Setup felt like decoding ancient hieroglyphics — totally unnecessary headache.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Concerns about counterfeit tools
I spent ~$1200 and have used the tool multiple times and don’t regret the purchase.
Concerns about subscription requirements for certain functionalities
how much more are you paying just to keep basic features every year?
How do I scan a QR code from an image in my camera roll?
Concern about functionality after subscription expiration
Really loving this thing so far, especially the bidirectional ability!
Discussion on the challenges of using dealership-specific tools
make sure with who ever you choose you really do the digging so you don’t end up hating what you used to enjoying doing like me.
Risks associated with tuning diesel trucks
Tuners can do a lot including fuck the truck up BIG time.
