It's been one of the best purchases that i've made. I wasnt using it to burn blu-rays at first, just read them and HD-DVDs as well as burning DVDs and CDs. More recently I've been burning Blu-rays and as expected it burned them with no problem and even at 4x speed which means 25GB takes about 15 minutes. The discs I've burned have worked in my BD player (LG-BD350) without fault.
If you're looking for a BD burner, you cant go wrong with this one.

one of the best valued blu ray writers/hd-dvd player there is. You get two HD players in one device for less than £150 i would recoment it to anyone and no software confilct with my vista pc.

thanks play.com

This is still one of the best valued blu ray writers/hd-dvd player there is. You get two HD players in one device for less than £200! If your confidant and have the right graphics card and monitor you will be amazed at what this can produce. The software included works pefectly and with a free download, it will even play copy protected Blu Ray AND HD-DVD discs! Ignore the comment below about colour issues because that is more likely to be down to graphics card/graphics card driver incompatability issues than the hardware. So if your confident with installing optical drives into to your computer you can grab a great bargin with this drive!
