OBDSTAR X300 DP vs. Xtool EZ500 Full System Diagnostic Pad

Looking for a good full-system diagnostic pad: OBDSTAR X300 DP and Xtool EZ500 (same as PS80), which one better? Look here:

Hardware specification:

X300 DP-1


X300 DP-2

Car list:

X300 DP-3

OBDSTAR X300 DP Review:

1.by all accounts its the dogs doodahs on anything Honda including rematching ecu after flat battery, and as it includes all the green units F100 to F109 it seems to have a lot of token free coverage including it claims Toyota G and H reset, if just 70% of the claimed coverage works then its a lot of programmer for the money and paid for and in profit after half a dozen jobs.

2.its one of those units that may or may not be top draw but is easy to get payback on

xtool ez500 review:

1.I’ve only had Xtool EZ500 full diagnostic system for a few days, and will update my review as I get more familiar with mine, but so far I’m very impressed.

2.I can confirm it will read PIN code & program keys for a 2008 Jeep Wrangler, and appears to be accessing all other modules on that vehicle.

3.I also connected it to a 2001 Ford Sport Trac and it seemed to access all functions well.Also, on both of these vehicles it appeared to work fast.

4.I test it and it can record and playback live data.

5.It is really good and when it can diagnosis reports in PDF file.

6.The unit appears to be built very well and has a solid, professional feel to it. Activating / registering it online was simple and only took a few minutes.

7.The carrying case is well designed and well built, and carries the scanner and all the adaptors, cables, charger, etc. very well (though for convenience I’ll probably get a small case just large enough for the scanner / cable / OBD2 adaptor / charger since that’s what I’ll be using 90% of the time.)

8.If it proves to be durable, I think it is well worth the price

In conclusion, both Obdstar x300 dp and Xtool ez500 from OBD2TOOL have their own merits and demerits. Both are good at OBDII diagnostic and special functions for cars (heavy duty truck), though it’s kind of different in details, e.g. there are some special functions for some models that Obdstar supports while Xtool cannot support and vice visa. Besides, Obdstar key master dp wins in hardware design.

So, Obdstar x300 dp or Xtool ez500? It depends, depending on your purpose (functions you need) and models you have.
