I have had them in the car for 2 years. Of those I got from a partnership left-right are much better. If you want cheap bulbs that last a long time, they are just what you need.

Previously, I didn't bother to search for something else. Now, these bulbs have taken the concept of consumables to another level. They were never very durable, but after their production shifted to Poland instead of Germany, I noticed a tremendous decline in quality. I'm tired of changing bulbs. My next order will be the simple Osram ones, 31.5% cheaper and may God help me. We'll see... Because even at 4 euros, with this durability, you can't call them an opportunity anymore.
