It works!
Other products failed. This product was effective in reattaching the rear-view mirror of my 2011 Kia Soul. Clear instructions and relatively simple to apply.

Did Not Work . I Feel Glue Was Bad Batch I Have Used Many Times In 60 Years But Did Not Work
I applied this stuff many times in past without issue. I first cleaned area with alcohol and drives completely. Than I applied towelette to are and placed mirror mount into place after I put glue provided which was sticky on outside of container before it was even open. I pressed button or holder into place and let sit overnight before I put mirror on as a precaution to let it dry better. To my shock mirror came off in my hand as i adjusted it. The glue had a yellowish tint to it. I thought these were clear from past uses. Possibly a bad batch

Clean your windshield first.
I had to cut the tip of applicator off to get the glue out which makes sense but in the directions I couldn’t find it. There is enough glue to do a couple mirrors if you needed too. Use some glass cleaner on your windshield to make sure the area is clean beforehand. Know which way the mirror bracket goes onto the windshield. I like the glue.

Works great! Strong Adhesive
Rearview mirror fell off many years ago, used this product to reattach. It held up over the years thru the warm and cold cycles. Just fell off a couple days ago, and reordered product.Simple instructions, strong adhesive, ease of use.

It leaks!
Not a good product. I saw that other reviewers were saying it leaked but I thought the odds would be in my favor because of ALL the great reviews. Nope! I want my money back!
