Works very well, connects to the car instantly, easy to use. It could be a little smaller, but my husband is still happy. I recommend it 100%.

Tested more than 10 times and so far it is stable and connects fast and reliable enough
Works fine the first time (with iPhone 16 on Octavia)
USB-A and USB-C cable can be connected on the infotainment side (has the advantage of greater portability to other cars compared to "flash" types)
Stable connection, CarPlay works without dropouts
Price (in discount for about 450 CZK)
the connection to the infotainment system is a little slower now, but that's because the device has to be connected first and then the mobile phone is connected. Up to 30 seconds max but everything runs (I didn't measure, maybe it's even earlier)
Compared to the "flash" versions, it is larger and needs a cable

Money wasted on a product of the level of Aliexpress
Nothing
So I'll start with a light, non-stick Velcro in the wrapper
Totally crashing, unstable connection
A short cable, so it will probably suck. If you try a different, longer cable - it doesn't work
The connection is so bad that it will mess up both your mobile and on-board computer
It'll make a real mess in your on-board computer. Our Golf Variant VIII took a while to recover

lovely design
does not work reliably
refuses to connect via BT to the iPhone 14 Plus, sometimes after a few minutes it starts to communicate with the car (Octavia IV) and seemingly works, but the iPhone does not see it as BT connected. It starts navigation from the phone, but when playing audio from the net it misses the signal and gets angry. But most of the time they don't connect at all.
I'm coming back. It is possible that with another phone and with Android it will work normally, I don't know, I haven't tried.

it works, after connection it is agile and reliable connection
the included Velcro for attachment is a good idea
connection takes quite a long time, a few tens of seconds, a minute, another adapter (AAWireless) managed it within 5s
total cheap processing

MG ZS car and Galaxy S23 Ultra phone.
Fast and seamless pairing.
It doesn't heat up in traffic!
Google maps for navigation and Spotify music - no lag.
It takes about 15% of your phone's battery to drive 70km. For longer distances, you still need a wireless charger.
