I have been a motor technician for 35 years & use various diagnostic scan tools daily at work, I bought the XTOOL InPlus IP616 Scan Tool for home use. The reasons for choosing the XTOOL InPlus IP616 Scan Tool were the price, free lifetime updates & the amount of functions provided. After receiving the scan tool I found the feel of the tool & materials used to be of good quality (equal quality to the high end tools I use daily in the motor trade). After charging the tool & switching on the initial set up was very easy including updating, the user interface is simple to use for experienced users or beginners, the scan tool has good processing power & runs quickly, it has more than enough functions for most users & works very well. The scan tool does not have Bi-directional ability's but most people will not need this function, I very rarely use this function at work & then only to activate EGR valves, cooling fans, windows or central locking, if you have a power probe & the know how this can be done without diagnostic equipment. The scan tool has a cable connection for the diagnostic socket on the vehicle rather than a Bluetooth one which I prefer as it is more reliable & safer to use. From now on Xtool is going to be my go-to brand as the tools are very good value, good quality & the customer service is excellent, customer support sent me an email after I received the tool just to check if I was happy with the product & if there was anything else they could help me, I found if you contact them you get a very fast reply with straight answers. I am very pleased & more than happy with my purchase.
