Not tested yet, I hope it will work ;)
After testting it with a functionnal 12V DC converter ( the 9V AC converter they sent me is not working ), the control is lighting up but the system is still not working. They told me it's because of 12V DC converter ( but I've doubt about it ), I will try to find a 9V AC converter and try again. If it's not working I'll open a dispute.

After testing, this item is not working at all, no output voltage. After contacting the seller, they promise they sent another one, I jope they're reliable and not laughing at me.
