### ⭐⭐⭐⭐⭐ Roadi ep21 EPB tool
*by J***R on April 28, 2014*

The product worked perfectly on a 2010 A4 quarto. OBDII plug was a little difficult to connect, but once connected the tool worked as advertised and was very easy to navigate.

### ⭐ Product arrived as promise. Was only able to use ...
*by M***5 on February 1, 2017*

Product arrived as promise. Was only able to use it once to replace a caliper. Now, the device will not connect to my ecu!

### ⭐⭐ Doesn't do what they say it will
*by D***I on October 1, 2014*

It did not work as expected. We repair a lot of VW products and when the new style parking brake sysytem ( the emergency brake and rear calipers are electronically operated ) we needed a tool to provide efficient and reliable service. We encountered many systems that this was not compatible with. That is the reason I rate it as just a fair product. We ended up purchasing another system that works perfectly. Usually 99 percent of the products I purchase through Amazon do the job well and cost effective. This time was not one of those.
