### ⭐⭐⭐⭐⭐ It's an amazing device, a must have!
*by V***Z on August 11, 2025*

This device is amazing, it let me fix the issues that my car had in less than 15 minutes. I did the fuse test and then I went to test the relays and I found that my relay EFI doesn't work properly. I just replaced the relay for 12 dollars and my car is working again. Video update after I got my new relay.
