Great communication by seller and seems like a high quality product with a braided line, heavy duty fan and overall robust structure which includes copper to help with heat dissipation. The globes are much brighter and have a whiter light than the originals. I highly recommend this this seller and give them 5 stars.

Fitted the globes and made a massive difference to my factory HID candlesticks!!
Hopefully they last the journey
Only negatives were the slightly loose fit (originals seemed really tight) - hoping they don’t dislodge from the rough Queensland roads!
