I've used them and price to performance they're ok, It's hard to justify $25 a bulb for silverstars, or worse yet the $80 I paid for the PIAAs I got in HK. The only thing I don't like about showoffs is the blue painted bulbs, the cops here don't like that. It makes your whole reflector look blue. To me, the money I spent on cheese bulbs before I got HID I could have had HID low beams, high beams, and fog lamps. I tried Nokya Arctic white and purple, the arctic white was nice, but not that bright. I've done PIAA Extreme white, and Super Plasma, both great color, but again OEM halogen was brighter, I tried blue, and purple showoffs, the purple were no joke, I swore I was going to get a ticket, they were just PURPLE..The blue were ok, but still not as bright as stock halogen(I have pics somewhere I'll try to dig them up). Now that good HID kits are getting down as low as $350 I'd love to see more folks save up and put HID in instead of wasting money on the bulbs. I had some guy on saturday that had me rolling. I pulled up next to him and my beam pattern just drowned his completely out, and he said "dayuuummn, what kind of bulbs are those", I said "HID", he replied "no, I mean what kind of bulbs are those", I answered "They are rebased osram d2r" and the moron responded "oh are those like silverstars" I almost pee'd myself laughing, thankfully the light turned green, I felt my brain melting away just being next to him. The whole purpose of all of these bulbs is to look "LIKE HID" why not just safe your dough and get the real deal? It's gotten so bad, people are fooled into believing that these fake bulbs are actually xenon, or HID, when if they have any xenon at all, it's solely used as a doping gas to change the color a tad. But they are still primarily halogen(most of the "xenon" bulbs are still as much as 90% halogen in them), the filament wouldn't burn if they didn't have enough halogen in them, xenon is used in HID bulbs because of it's properties of sustaining an arc, not because of it's color, the color in HID bulbs comes from the salts, and the electrodes, not the gas, and if the gas is effecting it, it's not by much. (except for the newest gen of bulb with the blue coating on them, which personally is cheesy to me)
