Query: Not worth buying no matter how cheap

My wife got me one of these for Christmas. I thought it would be decent for fast and easy rough backup of my old VHS tapes and TV shows. The first month it was OK. Made a few bad disks. Takes forever to startup and open tray. Operation could be simplified. OK, it's cheap. Picture quality not that great, but no worse than VHS. Constant humming sound when recording using its built-in TV tuner. OK, but it's cheap. I put up with all of these because I didn't expect much. Three months in, warranty gone, it started having difficulty reading its own disks. The longer you wait after recording, the worse its odds of reading it back. 4 months in, it started having difficulty even with store-bought DVDs, freezes even on its own menus, automatically skips ahead. Locks up when left alone. Tried installing firmware update and problems got worse. 5 months in and it lights up, but is as useful as a paperweight. Junk. Dirt cheap is pointless if it doesn't even poorly work.
