  Donald King: Like most others, I tried just about every OBDII apk out there. Piston works... That just about says it all, it works! The interface is nice, clean and simple to understand. Pairing went smoothly (even with a cheap $12 ebay reader), live data and snapshot data both work good. I have had no problem clearing codes and it just does what it is supposed to do! Sometimes just having something work well is a refreshing change given some of the questionable quality that shows up in the apk shop. I am very satisfied with this product and so far no annoying nags to purchase something more or make batter to receive features.

  Nicholas Paris: I was looking for a easy, clean, and functional reader for my odb2 scanner (elm327). This is by far the best apk. It pairs and let's you scan and search error codes in a matter of seconds! And the clean player interface is a nice plus. Perfect apk.

  Glenn Matthys: Works well, connected immediately with a BMW F20 + OBDLink LX Bluetooth. Dials would be nice, just numbers take too long to interpret, time that could be used to drive...

  Raija Browning: It has the newer material design, but it's missing a few preferred features. I will have to send an email to create the recommendations, but it in itself is a awesome apk.

  Eric Devi: Tried a lot of various apks, this one is by far the best..I'm a mechanic and use lots of high end scan programs, I.e.: tech2, modis, mdi....though no android/Bluetooth way of accessing data streams and dtcs even come close to the capabilities(yet) of the aforementioned scan tools,piston has the most straight forward ui and data display, than any another of the android/Bluetooth readers that I have tried..keep up the awesome work!

  A Google user: Robi dokładnie to co powinna, bez wodotrysków, reklam i innych udziwnień. Brakuje mi tylko możliwości zmiany kolorystyki (szare litery na jasnym tle nie zawsze są czytelne) oraz zapisywania danych live do pliku.
