Both of mine blew, and while they were brighter I wasn't going to fork another $160 to have a 100W low beam that lasted 6 months.
It wasn't the installation method - the globes were never touched at all, handled the entire time by the base (which isn't easy with the battery in the way but hey, it was $160 I'd spent ...). One lasted about 6 months and I put the original back in, then the other went at about 12-odd months. Philips to the rescue, a couple of years ago now, and no drama since then.
As someone else pointed out, for extra light at night driving lights are worth it. I have in total 560W of forward lights (not including parkers). I changed the H3 globes in my IPF halogen driving lights from 100W to 130W using cheap Supercheap globes and they've actually been superb. I have a 120W light bar and two 40W light bars as well. There's not a lot that I can miss when I turn it all on!
