Overall sentiment: negative
Customer reviews:
I did not have confidence in this. Plastic, one part glue. It works.

Update: lasted 6 months. Plastic could not support the weight of aftermarket mirror. Plastic cracked but held to the windshield very well. My advice, if you frequent dirt roads, go with metal. 
 Junk. Neither mounts fit the mirror I bought from the same brand. 
 1.  Cheap plastic.  After waiting the required 18 hours for the glue to dry, attached the mirror that has a set screw so mirror doesn't shake.  Turned the screw one time and the plastic rib broke.  Went to three local auto parts stores before finding a metal replacement.  B.  Glue doesn't hold.  It took me over an hour to slowly remove the flat button bracket from the windshield in order to install the wedge bracket.  After the wedge bracket broke, I had to remove it.  I assumed since it had now been over 24 hours since I had installed it, it would take a lot of work to get it off without breaking the windshield.  WRONG.  I placed a metal flat blade under the bracket and it came off with the easiest motion I could possible make.  If the bracket hadn't broken, the mirror would have been enough weight to pull the bracket off the windshield.  Save your two dollars.  Instead, donate it to the charity of your choice, or burn it in the fireplace.  It will take less effort and give you greater satisfaction.  3.  When I purchased the mirror, they had two choices.  One was the wedge mount and the other was the flat mount.  I had no idea which was which or which I needed.  It wasn't until I removed the old mirror that I found out I had purchased the wrong mirror for the bracket on my windshield.  At first I was glad I had spent the extra two dollars to get this kit.  It has both brackets.  But it might as well have had an old innertube for all the good it did.  I think a two year old teething baby could bite hard enough to break these in half and the glue won't hold water. 
 Glue was completely dried out and unusable 
 Plastic mirror mounts would not hold the mirror and the screw in the mirror to tight down went right through them and I had to remove it from the glass which I glued it to, and if you've never done this it is tough to do, took a while, if you had wanted it to stay on the glass it would have fell off, it held on the glass well but would not support the mirror. Would never purchase this again I ended up using a metal one. 
 absolute poop 
 How is that supposed to hold anything? 
 glue is great everything else is horrible 
 I got the glue, and It was dried crusty and unuable. Crappy product. DONT BUY this, its a waste of money 
 Followed the instructions exactly, even waited a little longer than directed.  Mounted the mirror, the mount came off the windshield when I started to adjust the mirror.  The glue was obviously not hardened, I left it on for several more days and it never hardened.  I have no idea how the product is supposed to work.
