It works fine on the windshield but it does not work on the dashboard which is where I wanted to put it.

I had one before and I loved it on previous vehicle. It does not work well on tinted window on my vehicle. Hard to see cling on

It will work on loose snow. But it will not work on frozen over snow that has melted and then froze up again. I bought this Sno Brum so that I won't damage the paint on my car when I am removing snow from it. But there are times that you need a scraper on the windshield to break up the icy snow.

and it works great for seeing all over the back. I got it for my wife because that vehicle does not have a backup camera like I had put on my 4 door F-150.
It makes a difference BUT don't try to put it on a vehicle that a 50 degree back window, it just won't work. It works on those windows that are almost vertical, not like your front windshield.

I purchased this to hold my LG Voyager, because my Jeep Liberty doesn't have a place that allows me to display the phone well when I am utilizing the navigation function.  This windshield mount works well, but when I am on excessively rough roads it will sometimes pop off the windshield.  I have found that if you wet the suction cup a little and then stick it to the glass it will hold much better.

Even though this doesn't work on my vehicle I am saving it for the next one that it does work on!

This baby works great when your windshield is warm. Not so hot (pun intended) when windshield is cold. It falls off a lot in winter. But 75% of year it's great

The blade on the passenger side doesn't conform to the windshield and leaves a large stripe of water right in the center of the wiping area. The blade I put on the driver's side is working fine. This is on a 2000 blazer.

it does work, you can stick it to your windshield, or use the adhesive stick it on the dash, but you should let the adhesive sit overnight to mold then put on the mount, hope this will last, so far its been 2 weeks the dash adhesive seem to be ripping halfway , doubt it going to last much longer
update: 3 weeks and the dashboard adhesive failed, so disappointed after seeing all these great reviews, if i knew this i would've just bought a vent mount, now i am using on as a windshield mount, hoping it'll last more longer than the ahesive

It didn't work for my windshield with two small cracks, one was a star shaped crack and the other a small line fracture. The filler didn't penetrate the crack as the instruction said it would.

When I tried to stick it to my dashboard, it wouldn't stay no matter how many times I tried. Works great sticking on the windshield, although my view is a little bit obstructed. Holds the phone in place very well, and I've got a bulky case on my LG G4.

Works fine so far.  It's on a Dodge Caravan, which has a plastic piece to glue to the glass.  Local auto parts kits won't stick to the plastic.  This kit provides a new plastic mount and plenty of glue which does stick to the plastic.

Just tried a small section of the windshield.  It did polish and get off the water spots but during the last rain, the wipers could not get the water off of the windshield in this area.  Not sure what happened whether it took off some protective coating making water smear or what but I will not be doing the rest of the windshield with this product.

I'm giving this item three stars because I bought it to clip on to my vent and it won't. I mean it will but then it flops down and is useless. I don't know what kind of car(s) they tested it on but it wasn't a Chevy truck, a BMW, or a Lexus SUV. However, the suction cup works well and I'm actually impressed with the spring mechanism that grips the phone. It feels pretty secure and I've driven on some pretty beat up roads (Forest Park near I-64 in St Louis (yeah, you know the road)) and it didn't phase it. Yet I can clip it in or release it with just one hand. The suction cup mounts allows up and down adjustments and also rotates and the part that grips the phone swivels so it can be pointed any number of angles. It was cheap, sorry, inexpensive and it feels like it didn't cost much to manufacture so I'll keep it for a while.

works good for phone but won't stick to dasboard or anything else in the car except the windshield.
not where I  wanted it to be.

I had problems when I got this product as I wasn't able to mount it neither my windshield nor my dashboard. I moistened the suction cup and worked for me at least on my windshield, I haven't tried on my dashboard yet.

The install is very easy and I didn't have any trouble putting it in. Also, the motor and operation is fine. But the glass vibrates while driving. It's not the housing, just the glass. I've tightened and loosened the mounting nuts and nothing works. This is my second one and they both did it. The vibration makes it so you can tell something is behind you, but it's hard to make out even what it is. If not for other car's headlights for identification, this would be almost useless.
