Are the chips expensive...?
It works well.
I wish the price would come down a bit more...

The way the case was made is completely unnecessary.
Since it's an aluminum plate, it conducts heat well.
Sturdy and good
Second time ordering this item. first did not arrive. second order still didn't arrive.
Item did not arrive.
I took 2 options, the dual one and the regular one, so I'm not sure which one to write a review about.
Dual mode works, the two chargers output 100W per charge. especially the steering wheel doesn't heat up. Charging took about 3 hours.
first 67W, then mentioned it and gave 100W.
