I haven't tried them but I do know that they are made in china. Stick with power plus nozzles from bosio. From this post: http://forums.tdiclub.com/showthread.php?t=174643&highlight=nozzles

They are made in China and resold by Sundiesel. Either the DSLA 150P 520 (205's) or DSLA150P502 (216's). And as for quality--well, I'll stay out of that, but the fact that Sundiesel buys them for $3.50/ea you can guess how much precision goes into making them. BTW, they will print anything you want on the nozzles, which is a big reason why you sould be careful about where nozzles are made.

Then again, from another poster in the same thread

The first set of .205's I bought were from eBay, they said made in Germany on them, but after two tanks my mileage dropped drastically.

I then bought some of Smog's .205's, my mileage went up after I installed them and I've been pleased ever since.

I also bought a set of Sprint 520's (.205's) for another car, nice product, although the person I had install & pop test the nozzles informed me that one of the nozzles were bad. He replaced it with one from his own stock supply so I wouldn't have any down time. So not even the famed Bosio nozzles are free of flaws

So they might be good, they might not be good. For the trouble I would just stick with a known quantity.

I don't think I am biased either way and I don't know how truthful online "facts" are. I am just going off feedback on various forums. Cheap nozzles will work and expensive nozzles may have defects. But if it's defective your engine will run rough. If it's just a poor design it'll run smoothly but it'll be smokey and may have less power.

You could get a star you could get a dud, but I would suggest going with a known quantity.
