Easy to install on Thule T-tracks, very good on the road, produces noise above 100 km/h and that under certain conditions. Wind, if the tires are fitted correctly, etc. Amazing purchase for its price. Even the mechanism that extends outward is very good and of high quality.

After 2 uses and a 3-hour trip, I have to say:
positives:
+they fit on any T-bar
+no noise at speeds of 130km/h, and I didn't notice a significant increase in fuel consumption
+very quick installation for those who don't want them permanently throughout the winter
+very easy placement of the skis, without having to climb onto the car anymore
+very economical considering it holds 6 skis and has a retractable base

negatives:
-sometimes it requires a little force to push/pull the "retractable" case, which I solved with a little WD40
-The T-type fastening screws are "short" (about 2cm), so you may need a replacement (Menabo Screws for Bars 4x M6x25 / 4x M6x35 / 4x M6x45) if you have a curved base to fit better

After a brief test, I have to say that it is a good and quality product, honest, well-made and functional, which does its job well. However, it is not excellent and I give it 4 stars instead of 5 stars for 2 very important and neglected details...
1) The fastening screws are "short" at 2cm, resulting in if the rack has a slight curvature (like mine), they do not reach and the brackets start with the risk of damaging the bolts, etc. Plus, it significantly increases the installation time, which would be 4-5 minutes and on a curved rack it becomes 30'+++
2) When the drawer returns to its position, it suddenly reveals an extremely sharp metal (which could have been softened) that is extremely dangerous due to the force of pushing, and I have already injured my hands. And yes, now I know and I will be careful, but what about the others who will use it?
