It is strong (for now)
Following the manual and waiting for dry periods of eqch steps,the outcome is great.My mirror in a Chevy Astro van is heavy.The weather....well..Dubai! 42C normally.So...the challenge is on.As the first day,I can say it is snug.After few moments of putting the metal button with the mirror on,I couldn t move it anymore.Left for overnight with some tape on it to release the weight a bit.Today I tested.Boy....it s not going to come off easily.

Do not waste your money
This is not working. Easily detached after even 24hours curing time. Followed the instruction exactly, but not working in my car. Do not buy this.

Unsure of effectiveness...
I followed instructions exactly as written. My mirror stayed up for a day, then fell off. I worked out this was due to the glass heating and softening the windscreen glue. I can't comment on the effectiveness of this product, as I purchased a differnt one in case, due to doubts. My advice is to remove the mirror from the metal plate it slides onto if you have to park your car on the street in the heat of the day, as some windscreen glues are not effective once the windscreen heats above certain temperatures. The temperature of the windscreen makes all the difference, especially in UAE.

Pega en menos de 5 segundos, lo mantienes con el dedo 30 segundos mas, y en media hora ya puedes instalar el espejo

This worked great for our fallen mirror. The package looked as if the product was leaking on the inside as other reviewers have mentioned. But we followed the directions and it worked perfectly. It's been several months in different temperatures, and it's holding solid
