I recently tested them on a long trip of about 1300 km. They were installed on a Suzuki Vitara 2025, in combination with the roof box https://www.skroutz.gr/s/35987359/ArtPlast-Roof-Box-Mpagaziera-Aytokinitou-me-Mono-Anoigma-CHoritikotitas-400lt-Anthraki-BA400.html. They look very much like, if not identical to, the Menabo Tiger (the box they arrived in had the word Tiger written on it). (https://www.skroutz.gr/s/58356977/Menabo-Tiger-Silver-Roof-Bars-Suzuki-Vitara-2015.html). The differences I notice are as follows:
1. There are no Menabo brand stickers.
2. There are no rubber strips to be placed on the underside of the bars (to cover the rail that remains empty).
The second point results in a loud whistling noise from the bars at speeds over 80 km/h. On my next trip, I will install the Menabo rubber and return with updated information. Also, the Menabo manual states a maximum speed of 130 km/h, while the leaflet accompanying the Carman bars states 65 MPH (~105 km/h). Personally, I did not exceed 110 km/h, because the noise from the bars and the roof box was very loud and made me feel very insecure. Nevertheless, the trip was completed without problems. During the trip, I tightened the bars again (as recommended in the manual), and they did indeed need retightening. For the above roof box, I have written a detailed review that is available. In the review for the roof box, I mention that it was installed on a Mazda 3 2010, with Hermes GS2 bars. The difference in noise was huge. On the Vitara, the noise started at 80 km/h and at 100+ it was (at least for me) worryingly loud. With the Mazda, I traveled at 120 km/h very comfortably and could have gone faster. Perhaps the noise is also affected by the car's aerodynamics. The Menabo manual states that the noise is reduced if the bars (and the roof box) are placed further back on the roof. On my next trip, I will place them further back, as the first time I couldn't accurately calculate so that the roof box wouldn't touch the Vitara's antenna. The plastic caps that go on the ends of the bars go on and off very easily. The corresponding Menabo ones seem to lock better. To be sure they wouldn't "fly off" during the trip, I put masking tape on the ends of the bars and then put on the plastic caps, which fit quite tightly. Overall, for occasional use 2-3 times a year, the bars do their job and prove to be of good quality and safe (taking into account the limitations mentioned in the manual). Also, their installation and removal is very easy and quick, with the Allen key included in the package. Considering their purchase price (€85), I think it was a pretty good choice. Note: To read the leaflet that comes with the bars you will need either very good eyes or a magnifying glass... Personally, I took a photo with my phone and then enlarged the image.
