About this product
The Ps90 Pro sits above a plain scanner in Launch's range because it is sold with programming and matching functions, and that is where the questions are: which modules on which brands can actually be written, and what the subscription behind the online programming costs once the included period ends. Before paying, ask for the coverage list by make and by function, because a tool that writes one brand well and only reads another is normal in this class. Then look at the hardware path, since programming needs a stable connection and a supply that holds voltage through the write, and a battery that sags mid-flash is the expensive failure. The kit contents matter as much, with the connector set and any adapters listed rather than assumed. What it will not do is program a module the manufacturer has protected, and the subscription terms and the function list are for the seller to confirm.

Pros & cons
Pros
- Programming and matching functions put it above a read-and-clear scanner
- The online path keeps the software current while the subscription runs
- Handheld with a screen, so the work happens at the car rather than at a bench
- Diagnosis, actuation and service functions in one box instead of three tools
Cons
- The subscription that keeps online programming working is a recurring cost, confirm the term
- Function coverage differs by brand, and writing a module is not the same as reading one
- A voltage drop during a write can brick a module, so a stable supply is mandatory
- Exact kit contents and the adapter set need confirming before you pay
