In my experience,
I have seen lg drive h22n, h55l, h58l, and others, break or became defective after a few years (4-5 years).
The writing quality of lg dvd-rw (but not blue-ray drive wich are better as far as i know) is slightly lower than other brands such as pioneer, nec\optiarc, but it’s not so bad.
Now I have one lg h22np20 from about 2 years and it works fine, for now!
I have also pioneer 109, wich is a very bad reader, not mine particularly, but all 109 are bad readers, but their burning fine.
The dvd-r and dvd+r burned with pio 109,
scanned with a tsst l633c, yes, i know that it’s not very good as drive for checking writing quality, I use it only for compare dvd burned using different drive,
have a slightly better quality than those burned using lgh22np20.
