Then be prepared to spend a bit more. Get an xTrons (or an Eonon if you can find it) if you need something that almost looks OEM. I have had a few in different cars and they always performed nicely. I have an xTrons in my ZT-T for about 1½ years and never even had to reset it.
You didn't really expect a unit not even 50 GBP would last long, did you?
