No support, won’t answer emails.

I purchased several softwares and spent hundreds of dollars and worked pretty well for me until I lost my device. The “Device change” option in the software should register my paid software to the new device I purchased so I don’t have to purchase the softwares again, this option will NOT work. I can’t access the software I paid for and they will not return my emails. I’ve emailed at least a dozen times over weeks.

No support.

Instead of giving support to their product, they want you to spend another $129 to buy their latest product. I spent $90 on this product, and it is now useless.

App wont work for HONDA OR MAZDA

I’ve purchased this last year; updated the app multiple times; it worked very well with Porsche; but not MAZDA nor HONDA.
Emailed the developers with zero responses from them.
