Small crack in the corner.  It works just like the original.

Ok.  Had a little crack in the corner.  Don't have enough time to wait another 3 weeks to get it so I kept it and it works.

It does what it was designed to do, it's not a complicated part, looks slightly different from the original, but it works, nothing else to say.

Was slightly cracked in one corner before even opening. But it still installed okay and serves its purpose until we get a new one. Wish it could have started without any cracks though.

This part is identical to the original. It fits well and works as it should. It arrived promptly and was well packed.

It works as expected... not hard to mess this up... It works, and would buy another if I break mine ;)

What can I say, it's identical to the original, but not broken.  Not that bad to install (the only diffuculty is with GM's packaging, not with the antenna) and then a few minutes later you have a working antenna again.

Our baby monitor cord started to fray, so we purchased this as a replacement. It works just as well as the original.

The mirror is ok. Smaller than the original. The mirror inside the casing seems to vibrate. But for a cheaper than dealer purchased mirror, it works just fine.

Works just like the original. Only fault I had was the charcoal, I'm guessing that's what it is, was crumbly and messy when I transferred it to the filter from the box but once I plugged the filter in, it flushed the crumbs out and works fine.

It works just as the original, print quality is good.

This is exactly like the one that came with the phone, which I stepped on and broke. I was happy to see this one works the same, because my first one lasted two years with no problems, so I expect this one to work great until I buy a new phone.

A little less quality part than the original, but for the price - what do you expect.  It works.

This works just as good as the original. The cord is much shorter than the original, but it still works fine.

It's the same as the original. The three stars is because the original fell apart after just a few years.

And I thought my garmin was shot.  Happened to look at the side connector and it was push in unable to make a connect.  Took a gamble and ordered this replacement holder and it worked.  This seems to exactly like the original.  Seen where others complain that they break easy.  This probably should not be used to mount as the removing and reinstalling thru the stud receptacle on the back is probably the cause of breaking.  Consider an alternate means of dashboad mounting.

I wish they had strengthened the weak spots in the original design. It works fine, but this one is going to crack too after a little while.

It functions good..just like the original one
