Please pay attention! We are selling professional diagnostic equipment and tools intended for professional use. Before you try to contact us remember that we are not providing any training of how to work with these tools and equipment. We can help you to solve problems if something is really not working, but if it’s working and you don’t know how to use it we can’t help you with this. We interact every day with a large community of our customers and we can’t allocate additional resources to answer questions that are not related with solving of real problems or troubleshooting. Thank you.
