I was burned on a burner, it has trouble burning and I dug a bit deeper in product reviews and saw that it is common with that model. At the time I didn't think much beyond the burn speed and didn't do enough research, so it was partly my fault but the guy was probably selling it to me because of those problems.
This was from these forums BTW. Other than that great experiences all around, especially considering I bought things like motherboards and every part to build a PC, which one might expect to have problems with.
