Packaging, construction and feel of the bulbs is very good. The overall brightness is good as well, not too bright and blinding for traffic. The bulbs themselves, however, aren't adjustable. I was lucky to still have a good enough beam pattern by not having to keep them in a 3 to 9 o'clock position but most vehicles will require adjustment. Otherwise the pattern and spread is good (i.e does not blind oncoming traffic), not sure about longevity as it's only been a few days but the overall quality is decent. Would recommend.
