I have bought older version (black case tablet) OBDSTAR X300 Pro4, only key programming.
My experiences...not bad, no so good...still not sure about, I'm the owner for a short time ...but..
For OPEL:
***Astra H 2009 Z17DTJ - can't read PIN from ECM, from DIS
display can't, also - so I've read handly from DIS 93c56, but coding PCF7941
toogether with remote afternarket key 2 buttons for a second !!!
For RENAULT:
***Kangoo 2008 1.5dci - can read PIN but do not needed for
coding...7946 remote 2 buttons aftermarket, immediately, like charm
***Clio
1.5dci_2004_UCH 93c66_PCF7936_aftermarket key 1 button_coding in a second! Also,
has an fantastic function-can solve UCH collision on one click and UCH is a live
again (in case you make bad coding or similar stupidity-tipically for my
self
For FIAT:
***Stilo_1.6_16V_IAW5NF.T1_3K91D read file and PIN, usefull if
you need to coding remote with MES or FES
For PEUGEOT:
***P206_1.4L_2002_Sagem 2000-2A_Siemens BSI-E0X, BSI-F0X read
eeprom, PIN, programming KD NB11 key for a second!
That's all, will update later more...please, do the same to share experiences...!!!

So OBDSTAR X300 Pro4 is not perfect but not that bad for that cost ...
