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!

Pretty much everything Liqui Moly produces is excellent. This being no exception.

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.

Works well
Ideal for fitting parts to a motorbike you would rather not lose on the way to wherever you're going.

Doskonały zamiennik dla Loctite 243, działa jak trzeba, śruby dobrze trzymają na gwincie.

Naar mijn mening duurt het lang voordat het droog is, maar het resultaat is goed
