Which K+DCAN cable to buy?

Below is a true review from a customer with BMW K+DCAN cable

I must say I am also a fan of the ‘One Stop Electronics’ cable. I had purchased a cheap K+DCan cable(there are even cheaper ones now!) years ago and it was ‘dead on arrival’ but I did not realize it until like 2 weeks of mind frazzling trouble shooting (a big freakin’ waste of time).
A professional OSE fan must do preparation work before purchase. This is my finding on a forum. Yes, K+DCan cable’s pcb borad. Only pcb can talks I think.

Then I got the this INPA K+Dcan cable at eobdtool.co.uk, by the link given in a post. Now, I have used it for months. It just worked (read&delete faults, coding, programming… What i tested is okay), and keeps working. The internal electronics, cable, and general materials are just higher quality with ‘craftsmanship’(which shows in the soldering of the OBD pins to their base PCB). See for yourself.

Below is the cable internal details. Very fine work, bridged soldering of 2 pins is intentional.

Below, note the dirty solder job(on the left PCB where the OBD pins are soldered). Turned out 2 OBD pins were NOT soldered properly to their base PCB and were detached.

Dead On Arrival-side B

The internal PCB looks nice and tidy, but again, this was ‘Dead On Arrival’. The main FTDI chip’s SMT job was also sloppy. Actually the FTDI chip’s plastic housing has been partially melted, due to heat from soldering the horribly placed LED pins right up against the main processor.

Dead On Arrival-side A

Regarding the cable, at first, I thought, ” What?! €15.99! unbelievable!” Then after 2-3 weeks of hair pulling/red buggyeyes/trouble shooting into oblivion etc.(due to the crap cable), and another 1-2 weeks or so of waiting(for shipping of the KDCAN cable), I thought, ” What a relief!”
