Personally I think the black ones look spot on! Not too bling, but very classy. I can't comment on the chrome as I haven't seen them yet!
Nothing so far has made me regret buying them, regarding the bulb issue I'd have rather the unit just came with the pre fitted bulbs which are correct and I'm sure would be perfectly adequate, it's more frustrating that the additional 'free' bulbs are not suitable for use IMO. It's is fully my choice to upgrade the lamps to the Philips xtreme 130% but it's much easier to do this before fitting the units - I want as much light as possible and they seem to be the right choice for me!
I'm exited to have one of the first sets to ship as I think these will be a popular choice and look fantastic. No disrespect but if everyone sat on the fence then we'd still all be driving with the crappy h4 units!
