sticky product

I tried it, it is nowhere near as easy to use as it is on video. The problem is that the product sticks to the fingers instead of sticking to the place of repair .... After a first try, I managed to adhere somehow a certain amount of product and it was still leaking. ... I'll try again ... It's not as easy as shown on the video .... It sticks to your fingers instead of sticking where it should! I found it hard to spread some and i'm sorry to say it was still leaking. I'll try again ....

Who has ever used it, why 5 stars?

Personally, I find the reviews curious, who has used that stuff in an emergency? So delivery etc etc is perfect, as is usually the case with SVB, but that says nothing about the product. I have it too and I hope never to use it, if so, I would like to add the product rating.

These ratings are not really helpful. A product can only really be rated once it has been used. Here you should really create a choice with which this can be expressed. Hope I never need it and can therefore not say anything about the quality and satisfaction.

small leak into a boat

We had a small drip into the hull in the summer. tried to apply Sealant LEAK HERO. We put quite a lot on the hole, kept dripping through. The only achievement was that when it came to glassing the hole everything was greasy from the Leak Hero.
Then we bought an under water epoxy stick which worked like a charm.

Completely useless! LEAK HERO gives a completely false sense of security!!!

I had a very small leak at the bow thruster (2 drops per second), at most 10 cm below the waterline. Leak Hero didn't work at all.

Leak Hero gives a completely false sense of security!!! - Completely useless! Fatal in an emergency!

Completely unusable

A tiny hole in the bridge deck needed to be sealed because water had penetrated the electrical system underneath.

The product sticks everywhere, especially to hands, but not where it's supposed to.

Not in dry conditions, and certainly not in damp conditions. It's unthinkable if a serious leak were to occur and we had to resort to this extremely defective product. The can goes in the trash. Rating: 0 points; in my opinion, it's even a safety risk. It should be withdrawn from sale.

I also don't understand how anyone can give it a full score without ever having tried the product.

** wir bedauern sehr, dass Sie mit unserem Produkt YC Leak Hero in der Anwendung nicht die gewünschten Ergebnisse erzielen konnten. Wie Sie beschrieben haben, wollten Sie ein kleines Loch mit Fett verschließen. Dabei kam es jedoch zu einer unerwarteten und für Sie ärgerlichen Situation, da Ihre Hände stark mit Fett in Kontakt kamen. Wir verstehen, dass dies für Sie sehr unangenehm war und Ihr eigentliches Anliegen dadurch in den Hintergrund geraten ist.

Da es sich offenbar um einen sehr speziellen Anwendungsfall handelt, bedauern wir, dass das Fett in diesem Fall nicht die gewünschte Haftung entwickeln konnte. Grundsätzlich ist es so konzipiert, dass es auf nahezu allen Untergründen haftet und als Notfallhilfe dient.

Sollte ein Schaden wie ein kleines Loch bereits im Vorfeld erkennbar sein, empfehlen wir grundsätzlich, sich auch professionelle Unterstützung zu holen, um eine dauerhafte Lösung sicherzustellen.

Wir hoffen dennoch, dass Sie inzwischen eine gute Lösung für Ihr Anliegen gefunden haben.

Not good!

Due to the welder's lack of qualifications, we had a small hole in the water tank lid that we wanted to seal with LeakHero. We pressed a nut-sized piece of sealant onto the 5mm hole. The sealant isn't good for anything; it just keeps leaking out.

Actually 0 stars

Product belongs in the trash.
At first it seems like a "miracle cure". But then you quickly realize that even with various methods of pressing the product on, it doesn't stick. Instead, it sticks to your hand.
The words "easily washable" definitely don't apply to Leakhero.
And that for €36.
A DISGRACE!

Too good to be true

If it sounds too good to be true, it is. I tried it on a leaking joint in the fresh water system, but the joint began to leak again as soon as the pump was turned on. It is very unlikely that the stuff would withstand water pressure below the waterline, at least I have no faith in it.

Do not bake underwater (eg antifouling)! Do not think that you can seal something with it against pressing water! Is ecklig on the hands!
