Well, I've used it about 10 times so far and I have to say it is great. I've only used memorex 4x dvd+r and hp dvd+rw on it. With the memorex 4x's, it writes at 4x steady. Takes about 13 minutes to burn a dvd. Thing is so quiet it's unreal. If it wasn't for the red light on, you would hardly know it's burning. Used Imgtool Burn on all my dvd's and my pioneer DV434 hasn't hiccupped yet. Haven't used it to rip much as I have a dvd reader also so other than what I wrote above, I can't comment on it. There's also a updated firmware for it. Says more disk compatible. Hope this helps those interested in it. Bear
