Scam Warning

This company will charge you $116.88 for sone fake yearly subscription years after you bought the device.

THIS IS A SCAM COMPANY!!!

Auto renew default to on

Thought the app was alright for coding and diagnostic, however I found the information was very limited with any of the codes. For you to understand the codes in more depth, you’d need to pay extra once more! moved to Carista as had a better experience. Out of the blue, another annual payment gets made, even after cancelling the transaction from my back they have still taken the money out and shock horror “no refunds”. They state it needs to be cancelled 30 days before billing.

Completely lost all respect for this company, wouldn’t recommend at all. Would recommend ODBeleven, Carista or even taking your car to your local garage rather than using this company.

Seriously ?

I am sat in my 2029 Mercedes e class with the EML light on. I plug in the Carly unit - immediately the car complains about reduced Command functionality but I press on. Wait for the Carly unit to update as I haven’t used it for a while and then I run the diagnostics - all sytems are green ! How can this be right when the car is clearly displaying an issue.
