Good stuff
Had a bolt on a 125 motorcycle that would vibrate itself loose every 50 miles or so. Applied this and had been holding it great last 300 miles. Recommend!

Bottle is *supposed* to be mostly empty
Good quality product. Unlike some other reviewers, I read the documentation on the LiquiMoly website for the product. It explicitly says in the documentation, in red text, that there must always be lots of air in the container to avoid premature hardening - the product hardens in the presence of metals but the *absence* of air. Therefore the bottle is larger than it might otherwise be. You will still get your 10g of product in it.

Next to nothing inside
I’m not sure what happened here but there was basically no glue in the bottle I received. When squeezed fully and upside down some liquid is visible, but very little. Seems like it was sealed maybe there is a bad batch as I had a look at recent reviews and noticed that a couple of others have had a similar issue. 3 stars because I’m not sure if the glue is effective or not, thin’ I just got unlucky.

Absolutely perfect
I was having issues with the bolts on my BMW Z3 rear arms coming loose, this did the trick and they haven’t loosened off at all since. Must have for any mechanic’s toolbox / toolbag.

Frein-filet de très bonne qualité, utilisé pour sécuriser les vis maintenant mes sacoches sur la moto, ne bougent absolument malgré les vibrations. très bonne tenue dans le temps, aucun problème. Démontage pas trop difficile avec les bons outils. Flacon pratique et facile à utiliser. Un très très bon frein-filet.

Ich habe die LIQUI MOLY Schraubensicherung (mittelfest) jetzt mehrfach im Einsatz gehabt und bin sehr zufrieden mit der Leistung. Die Anwendung ist unkompliziert: Einfach ein kleiner Tropfen auf das Gewinde und die Schraube hält zuverlässig fest, ohne sich durch Vibrationen zu lösen. Gerade bei Arbeiten am Auto oder Motorrad gibt mir das ein gutes Gefühl, dass sich nichts unbeabsichtigt lockert. Trotz der sicheren Fixierung lassen sich die Schrauben bei Bedarf noch problemlos mit normalem Werkzeug lösen – genau so, wie man es von einer mittelfesten Schraubensicherung erwartet. Die 10 g Tube ist handlich und reicht für viele Anwendungen aus, da man wirklich nur wenig Produkt benötigt. Die Qualität wirkt insgesamt sehr hochwertig, typisch für LIQUI MOLY. Fazit: Zuverlässige Schraubensicherung für alle, die Wert auf sichere Verbindungen legen, ohne auf spätere Demontage verzichten zu müssen. Klare Empfehlung!
