Works well for sending my xperia z picture to the tv. However on occasions the signal would be lost and I had to unplug the adapter from the phone and re-plug in to get the picture back. Otherwise a clever and nice little addition to your xperia z. Also like the fact it charges the phone while plugged in so battery life isn't an issue.
Worked perfectly on my mk4 golf. Having changed the pads before without the tool (and struggled) I thought it time to save time and effort this time round. So please I did as one caliper was slightly seazed and this tool meant i could get so torque twisting the piston in (using a ring spanner on the end of it). Really, really happy.
