Using this with a nexus4.
Haven't tried the window or dash attachment.

Worked well, where other mounts fall down. Took a while to figure out how to CLIP it properly- you really have to get it DEEP into the vent.

This works mostly as expected.  Does what I wanted it to do.  It holds a TV well.  My only complaint is that I needed to have my TV angled down the maximum amount.  When you do that two things happen.  1) My rear-facing HDMI plugs press into the mount and breaks them, so I had to get new cables and 90 degree HDMI corners.  2) There are screws in the bottom to help hold this all together, they're not really necessary, just nice to make everything a bit more sturdy, and they're impossible to get to if you've angled this down all the way.  But the mount is cheap and nice for the price.  If you don't need to angle your TV downward or to the side and just want a cheap wall mount that will hold a TV flat against the wall then this is for you.  I've actually ordered another one that I'll also be tilting downward all the way, but I'll just use more of the 90 degree HDMI corner thingies and don't really care about the bottom screws not being able to be secured.

Agree with most of the reviews that state this isn't a very good solution by itself for ceiling-mounted vents.  It barely has enough magnetism to stick without the vent blowing.  However, I did find that by supplementing it with&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/30-Neodymium-Magnets-1-4-x-1-16-inch-Disc-N48/dp/B001KUWM3C/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">30 Neodymium Magnets 1/4 x 1/16 inch Disc N48</a>, it works pretty well.

Works great, but the position that it must be placed in is not ideal (at least for my car). Magnet is strong so phone stays put and rarely falls off. Nice product but needs a better attachment piece so it can go into the venting ducts rather than the vent control.

There is an inherent design flaw.  My phone (Samsung S4 Mini) weighs more than the vent can carry.  I have a Subaru and put it on the last vent edge, but am still not able to change the direction of the vent, while it's in place.

This mount is great although it is a bit tall for mounting in a shallow hood channel. The height causes there to be more flex than I would like. Sinking an extra screw into the center hole does help.

The vent mount attachment works but is a bit wobbly and the vent bounces up on bumps.  As a result I did not feel comfortable using it for my phone.  The suction cup mount works perfectly and has two adjustment points that can be tightened up so your phone position will not move.  The included plastic disk attached firmly to my dashboard and allowed me to mount the suction cup holder exactly where I wanted it.  I like how you can rotate the phone to either be upright or on its side.  I have a Samsung Captivate and the adjustable side arms hold it tight without blocking any of the side buttons on the phone.  The Captivate is also tall enough that the rear speaker is not covered.

Hard to position in the air vent, but overall pretty good.

The unit adhered to the tiles well and was the right size for our shower head.  However, there doesn't seem to be a way to adjust the angle of the shower head.  Also, the directions were somewhat unclear.  I was more pleased with a less expensive  shower head holder that has angle adjustments.

Does what it says, however the air vent application is not as secure as the others. Once the weight of the product and phone are combined it eventually tends to sag down and has to be readjusted periodically.

Has the perfect angle. This is the second one we purchased, the first one was pointed way to high. You couldn't spray it down far enough to get it off of you when needed. The only issue with this unit is the larger diameter end that goes through the wall won't fit into the hole for a standard pipe. The original hole will need to be enlarged a bit.

it works well, but they should have a longer bit holder for hard to reach ceilings etc. overall a decent product

so far so good. the adjust-ability is a nice touch. comes with two pieces of metal on with a sticker.

Great magnetic strength. fits on the vents without a problem.

Love this, however, the vent clips don't really stay clasped very well for very long so after a few turns in the car, it starts to jostle.  Over all, it works well for me.

I'm very short and needed an extender for my car.  This works well.  Especially since you can set it at different angles easily while driving.  It would be better if it was a little darker though - that's why only 4 stars.  Have only had it a short time but seems to be sturdy.

This is a neat idea, but it will all depend on the details of your vents.  In my Toyota, the slope of my vents made it tricky to get a good angle.  Also, because the vents are designed to rotate easily, the GPS slipped around, making it harder to use.  Last, but not least, the GPS blocked the airflow from the vent, which naturally is the main vent for the driver (and I really missed it during this summer's heat wave).

Having said that, I really like the convenience of having the GPS in the same vertical plane as my radio and other controls, rather way up by the windshield.  When attached to the vent, I can control the GPS as simply as tuning the radio, rather than leaning up to reach the windshield mount.  Also, the GPS is much less visible from outside the vehicle (yes, I've had a GPS stolen from my windshield before, when my daughter forgot to lock the car).

I prefer the solid feel of the traditional windshield suction mount, and wish this vent mount didn't allow the GPS to wiggle around as much, but the convenience of a dashboard location outweighs the wiggle factor for me.  The device is very cheap, so the experiment is low cost and I can switch back easily (I've already tried removing the mount from the air vents, and it comes off easily).
