The THINKDIAG is a powerful device enabling OE level diagnostics from your Android or iOS device including active tests and special functions via a Bluetooth OBD2 adapter and a app on your smartphone or tablet. In early 2020, there wasn't any European based distributors of the THINKDIAG but we were dedicated to change this as we wanted to give consumers an alternative to buying from Asia or America.

We are now one of the largest European based distributors of THINKDIAG OBD2 devices. Our company is run by myself Emma Brown, we are based in Stoke-On-Trent in the United Kingdom and all of our stock is also in the UK, as a result of us sending from the UK some countries may charge you import fees so we advise you to check your countries import tariffs before ordering to make sure you are fully aware of any additional costs that you may receive, if you need any information from us to help you with this please do message us.

For anyone located outside the UK or Europe we recommend that you take a look at mythinkcar.com as they are like ourselves, a safe trustworthy company to deal with that will give you good service and they will normally dispatch and deliver your order faster than asia based sellers unless you yourself are located in Asia.
