I bought an Amazon Warehouse version of this turntable, meaning it had already been opened, so this may have been the previous users fault, but I had to adjust the cartridge (which took me quite a while) to get the tracking just right.
Setup was complicated and the instructions were a little unclear, but there's a video online for a renamed version of this turntable that explained it in great detail.
After the setup, it's great! I don't personally use the Bluetooth, so I can't vouch for that, but the line out sounds great, and the USB output sounds okay. Unless you're using very expensive headphones like me, you won't notice a problem.
Overall just a nice turntable for those who just want to listen to records without all the fuss. Lenco, please try to record a video like your competitor did next time - It's really helpful to see someone set it up.
Below is a video of the setup for a turntable that's the same design with a different logo on it, for those who need it.
