This works OK and you are able to perform dtc scans etc. but not much function, and it is seeing errors were there are none but I'm checking a Mercedes and they don't play well. Also missing live data and no ability to for example force a dog Regen. So as I said it is OK for basic stuff and very easy to use. One more thing once it is in the diag socket OMG it is a bugger to get out it is rounded and slippy had to put on my rubber work gloves to wiggle it out even then it was a struggle...
