The CS4 gives you four advanced features found on new cars and trucks as lifetime programs. So you can clear the oil warning after changing oil for instance or reset your TPMS. For other features such as ABS Bleeding as example, you have to use the store and pay 29.95 for it and it's only for a year subscription. So after a year, you have to pay up again. This is on par with other scanners though. Though note that each advanced feature you may need that isn't part of the main four given, is 29.95 a year.. Each. If you are a mechanic, that wouldn't be much of an issue with the ROI from using it more often. DIY though, its kind of a bummer. For me my Chevy Blazer is a 2001 so I really don't need the more advanced features and note that not all features will work with every make and model so you have to check first. The store itself is easy to navigate and look up the different programs to add for purchase has has a review section for each. A glaring issue I find though is there isn't much info about each one and of any known compatible makes and models. You'll actually find some folks saying how they paid for the feature and find it didn't work for them. So keep that in mind. Though the scanner itself though for what it has already is great and was able to find a few codes relating to my dreaded P0300 issue and found that my ABS module is having an issue (common for my vehicle) and that my airbag system is perfectly fine. You can also view live data as well as freeze frame data and customize exactly what you want to look at. So for me I set it up to show me live data for all cylinders and their history. I found that cylinder 3 and 6 are misfiring with high counts. I can then make a report of it and save it as a pdf or email the report to myself or if you're a professional mechanic can send to your customer's email. On the scanner itself on top under a dust cover you'll find a usb-c connector (a usb-c cable is included) and a micro SD card slot. Now for the USB C connector you can use the included cable to connect the scanner to your PC or laptop to get any files from it. The micro SD card slot though I've found it not to be working or at least not with the 64GB card I tried with it. I inserted it and nothing popped up as if it recognized it and going into the file manager only shows internal memory and no external SD card memory. This could be an issue with the slot itself or simply its picky about which micro SD card it'll take. But is something to be thoughtful if you plan to use sdcard to move files. Another glaring issue I find though is while the box it comes in is quite nice, it's also your case. There is no included soft or hard case which for a scanner that is going to possibly be in a shop or heck even at home, I feel a case is more than necessary for a device such as this. In a shop, that box alone isn't going to last. So other than a couple pitfalls that I've found, as an advanced Scanner to help me diagnose issues beyond just OBDII such as ABS, it does the job perfectly in my opinion. Oh also I forgot to mention that in the store they have a points system. You can "check in" every day through the store while connected to wifi and for every 3rd day you get 1 point. You automatically get 5 points. Each point acts as 1usd. So remember that subscription price of 29.95 for each advanced program? That means right off the bat you can save 5 usd off the price or if you saved up 30 points, you should be able to technically get the year subscription for the selected feature at no extra cost. You don't have to hook up the scanner to a vehicle either just to power it on and check on every day for the points. Simply connect the Usb-c cable to a USB power adapter like the one that comes with your phone and it'll power up with it. So overall I would suggest this scanner. It would make an excellent gift for a DIY weekend warrior or a mechanic friend or family member who could use one.

This was a gift to my fiancé and he loves it. He said it’s a great tool and much better than any other diagnostic tool he has used.

Gutes Teil … Updates ohne Probleme und schnell… Preis und Bewertungen auf anderen Seiten sind sehr gut… kann man empfehlen

Dieses Diagnosegerät macht und kann all das, was in der Gerätebeschreibung steht. Super! Schade ist nur, dass eine Aufbewahrungstasche nicht dabei ist.

Für Hobbyschrauber mehr als ausreichend, einfache Bedienbarkeit, gute Funktionen und Auslesebarkeit von ISTwerten, zu empfehlen

This was my first scanner .What a great choice! Cleared codes and check engine light went off and running live stream data 90 miles before inspection helped pass the vehicle! A+!

Works well with Sorento UM. Successfully resets EPB to 0 position so brake pads can be replaced. Price is also acceptable

Ist sehr gut und zeigt vieles an

Das Gerät ist perfekt

Sehr gutes Gerät funktioniert wie beschrieben komme sehr gut zurecht und einwandfrei
