Worked well
Bit pricey, but worked well, follow instructions , clean tabs , and area to be applied, worked within 1 min to bond whilst holding it in place. Left it over night, all working again good product .

Failed Despite Following Instructions
This is the second time I’ve tried this product and it’s failed both times. It simply does not bond to the circuit. I’ve followed each step of the instructions to the letter, but when I came to attach the connector the follow day, it came away from the window. Really disappointing.

Clean conductive strip on screen well before re-attaching pad.
Easy to use and worked just as they said it would. My heated rear window works just as it should.

Works if you follow the instructions
I bought this to re-fix the connector tabs to the rear window demister on a Toyota Aygo hatchback. The instructions are straightforward but very specific about the steps to follow, the amount of adhesive to use, etc. I followed them exactly (eg using only a small drop of adhesive) and the tabs stuck fine. I checked the electrical conductivity after leaving to dry for 24 hours and that's okay too. The only concern I had was that such a small amount of adhesive would provide too little physical strength under normal wear-and-tear on a hatchback window. So once the specialist conductive adhesive had dried I added an additional layer of Gorilla Epoxy adhesive over the top of the tabs and immediate surrounding area of element to form a little "bubble" of adhesive holding the tabs to the surrounding element. This cost a couple of £s extra but makes it a really strong bond that should be permanent.

Epoxy great, conductive not so much
After following the instructions, reattaching the demister connector was nice and easy, appears to be stuck incredibly well, after a day to cure I wanted to test the connection to ensure it worked as expected. Sadly could find no continuity between the demister. Tested the remaining adhesive compound and found the same lack of continuity, so not sure what’s going on there, but now have to try and resolve how to bridge the demister to the connector, which is a little frustrating.

Fonctionne super bien j'ai réparé la prise de dégivrage arrière sur ma 206 RC sans probleme.

Deze elektrisch geleidende lijm doet wat hij moet doen. Goed de gebruiksaanwijzing volgen. Ik heb er nadien nog extra 2 componentenlijm over gezet. Best langer vasthouden dan 1 minuut tot je voelt dat hij plots uithardt. De verpakking is klein maar meer heb je niet nodig. Zo blijft de prijs van de reparatie betaalbaar. Toch best niet aan de tabs trekken maar deze tegen de ruit duwen en dan de contacten aftrekken.

Fixed my Jeep Wrangler easily with this after a defroster lead tab broke off. Make sure you do this in room temp or higher or it probably won't cure. *Update* Didn't make it through the fall, let alone winter. POS. Will be looking for something different.
