more grippy than bean bag mount
355986
I have both the bean bag mount and "this mount"(for lack of a better name).  Whereas the underside of the bean bag mount is made of neoprene rubber foam, this mount is made of very grippy solid gel-like silicone rubber.  The base of this mount is moldable to conform to the contours of the dashboard.  On my Toyota Echo, which has a steeply sloping dashboard, the bean bag mount slides down after a few bumps on the road.  This mount on the other hand stays put on my Echo.  The main drawback with this mount is the silicone base leaves a greasy residue on the dashboard.  The residue is noticeable but does not really annoy me.  If that's the tradeoff for a very grippy mount, I'm okay with this tradeoff.  It's less stable than the wider bean bag mount because this mount has a narrower profile.  When I place it on the passenger seat, it can tip over, but does not tip over when placed on the dashboard.  The bean bag mount on the other hand is totally stable and doesn't ever tip over.

Summary:

Bean bag mount:  no residues on dash board, but less grippy and can slip on steeply sloping dashboards, stable and does not ever tip over.

This mount with silicone rubber base:  leaves silicone oil residue on the dashboard, much more grippy, but less stable and can potentially tip over.

I prefer this silicone rubber mount because of the steeply sloping dashboard on my Echo.  Otherwise, if my car had a fairly flat dashboard, I'd prefer the bean bag mount because it's more stable when placed on the passenger seat.

Wouldn't stick on my 2 vehicle ('95 4runner and 2000 Jetta), maybe because of the curved windshield. Bought the bean bag and am very happy with that. It's the way to go IMHO. You can than hide it when you leave the car leaving no telltale apparatus to tempt thieves.

My dash board is not a smooth flat surface, it slopes every which direction and has a rough finish making it impossible for my GPS to adhere to it. My personal preference is not to have something in the center blocking my view, so this allowed me to place the GPS unit in the corner or anywhere else. The mount doesn't slide around, and the smooth center is plenty big enough for the suction cup of the GPS bracket. It is pretty big though, but tucked into the corner, I don't notice.

I ordered this product as a replacement for the "as seen on TV" windshield mount that has a sticky surface.  Unfortunately, my "as seen on TV" that can grip any phone securely, cannot grip phones with curved backs.  Hence, the search for either a custom holder for my Moto X or a universal mount.

I was very pleasantly surprised to receive the GEARONIC a week ahead of schedule.  It has a much shorter arm than the previous mount and tended to stay put with the phone in it's strong grip.  I have a very capable Isuzu SUV with a very tight suspension.  I can feel every bump in the road.  The GEARONIC is able to lock my phone in place and keep it very secure, even in an off-road excursion.

I've had the unit one week with a short trip out of town and it was very capable.  I was actually expecting much less from it due to the low cost, and have been very happy with the performance so far.  Since it will be summer in Florida soon, I will continue to report on how the mount holds up, but I am about to buy another one as a back-up just in case.  I rent vehicles often and tend to lose items such as this.

For what it is and how much it costs, I would say that you are getting much more than your money's worth.

Pros:
Strong grip holds my Moto secure
Short arm prevents too much bounce
Suction cup has a twist to lock mechanism
Excellent for horizontal/landscape mounting of phone
Ample silicon pads protect my phone when in the grip

Cons:
I feel that I could break the plastic grip if handled it without care
Adequate for vertical/portrait mounting of phone as the phone isn't able to face directly at you

Excellent gripping strength from the suction cap. Unlike my previous phone dashmount, it never lets go even on very hot days. It might be a little too good, I can't seem to get it off, but that's okay since I don't plan on moving it often. The phone 'clamp' holds both my 5" cellphone and my wife's 4" cellphone equally well and they never seem likely to pop out accidentally.

The nut that sits behind the clamp and controls/tightens the ball joint is a little hard to access when my larger phone is in place, but it can be done. I find that its a bit hard to find a good tension for that nut that allows for landscape to portrait rotation while still holding strongly once in the new position, so instead I just loosen the nut a bit, re-position and then tighten.

Overall very happy, but I would also like the option to have the pivoting arm be a little longer (either as an optional replacement piece or perhaps iOttie could make another dashmount available with a longer arm), since I have to reach a little more than I would like to touch the phone in some cases. Regardless, the best dashmount phone holder I've used so far.

Nice mount. It has the capability of attaching to many different diameter tubes so don't worry about it not fitting on your handle bars. The springy side pieces are nice if you want your phone to be quickly removable, but I found them to be in an inconvenient spot as they hit the volume down button on my Nexus 5x. When the silicone strap is on, it it keeps it just above the button so it doesn't hit it.  The plastic appears to be of average quality.  It does want I wanted it to do, so no real complaints here.

This beanbag offers a stable platform to hold the standard TomTom support's suction cup. However, the standard TomTom mounting arm is pretty short and doesn't leave much room to access the USB connector while on the bag. So, if you want to keep your TomTom plugged in to the car's power outlet while it is attached to the bag, you may want to consider TomTom's alternative mounting kit (approx $30), which has a longer arm, making it easier to attach and detach the USB connector.
The beanbag looks well made - the metal plate is held in place by four set screws, which presumably means you could remove/replace it (though I'm not sure why you'd want to!)
The manufacturer recommends mounting the beanbag diagonally (with a corner facing travel direction) for optimal stability. Presumably that maximizes how much of the bag's friction is available to counteract forward motion. That's worth bearing in mind depending on the depth of your dash.

I'm very pleased at how well this mount was able to hold my Nexus 6 w/ case. Other mounts I've tried couldn't open wide enough to accommodate the phone even without the case. The suction cup/sticky pad hybrid works really well on my textured dashboard .

I purchased the Easy View 2 almost a year ago. Recently, the cushion pads on grips of the mount came off (Damn South Florida heat). I requested just replacement pads for this from iOttie's customer support. I was surprised that I received an entirely new, replacement mount within a week. Just based on this alone can I recommend iOttie.

I really like this mount  -- it holds my GPS or my Samsung snugly, without crushing or marring --- it can be turned either Landscape or Portrait. It's secure enough not to slide on my dash -  fits nicely under my car seat when not in use.  There is no sticky bottom to it, no suction needed and can be placed on practically any flat surface.  It's versatile enough to hold nearly any phone or GPS, so there is little need to pay extra for a specialized mount...  Simply open the padded claws, insert your device. set it on your dash and you are good to go..

Simple and easy - I've used it without problems for my Garmin uvi , Magellan RoadMate and Android phones..

Solid, very solid mount. Does not bounce around like the goose-necks. Fits on my dash, and nicely on the left side window (center is illegal in CA). Only problem so far is that is has come off of the provided mount a few times, but a quick clean with a moist cloth and it is working well again. Can see my GPS and other maps very well from my iPhone 4.
One other issue is that the bottom pads do block the speakers a bit, but it only reduces the sound a little.

I bought this mount so that I could attach my new TomTom 730 to the Braketron beanbag mount for the dashboard of my car. (The supplied windshield mount won't let you mount it on a dashboard in a way that lets you see the screen). The mount is quite adjustable vertically. The end that attaches to the GPS allows some sideways movement and a small amount of fore and aft tilt. It comes with three different mounting plates for different brands of GPS devices. Check the company web site to see if this mount is suitable for your GPS. Sadly it does not solidly connect to my TomTom GO 730 (which is why I gave it a 3 - it would probably rate higher with a different device). Although the GPS will attach to it, it does not take much effort to pop the GPS off of the mount (say when you're trying to fine tune the angle of view and your hand happens to push the GPS).
It connects solidly to the Braketron.

As other reviewers have stated, this is probably the best quality mount available. Is it overkill? Maybe, but I prefer products that will last - and this one will. It looks cool and fastens securely to my windscreen. No bouncing around. Only negative is that it takes two hands to attach and detach the phone. Perhaps there's a way to do it one-handed, but in the couple of weeks I've owned this, I can't figure out how. Other than that, it's a great product.

These really do grip items quite well and securely.  The rubber materials is very tough and looks like it'll hold up well under repeated use.  One thing that concerns me is the base where the mount hole is has no reinforcing.  It should have a small metal plate/washer to keep the mounting screw/bolt head from digging into the rubber over time.  I had to fabricate my own by using metal snips to square off the sides of a couple washers.

I needed a mounting disc to use with a suction arm car mount for my phone. My dashboard ('07 Scion tC) has a ridged texture that doesn't allow smooth suction cups (those meant for glass) to stick. I couldn't find a mounting arm with the soft sticky gel type suction cups, so I settled for this semi-permanent solution.

It does what it needs to and application is straightforward, but after a few weeks of use the heat and weight of the mounting arm started to loosen the adhesive and the disk started to lift at the back. Here's the interesting part: the adhesive didn't weaken where the tape touches the dashboard, no, it instead weakened where the *tape touches the mounting disk*. So if the separation had continued, I would end up with a dashboard with the mounting tape still stuck to it, and an separate plastic disk.

I was able to fix the problem by simply applying some super glue with a thin toothpick to the growing gap between the tape and mounting disk. After that cured the tape and disk never separated again. Please note I also use a sunscreen for my windshield when I park in direct sunlight though. It's been about a year since I installed the disc and it still works fine.

NOTE: if your mount's suction cup is 70mm wide then you should get the larger 80mm size Arkon mounting disk because these disks have a rough textured border that's a few mm wide and they don't play well with smooth suction cups. So the actual smooth surface of the disk is a bit smaller than the actual width of the disk.

Bulky but this thing holds like there is no tomorrow. Its about twice the size of the stock mounts so i wouldnt say its the best looking mount but its incredibly sticky and works very well. One thing that was nice is it came with a baseplate for the suction mount if you are looking to mount this on something other than glass. Nice touch.

After getting my new Panasonic camera and trying to take pictures from my car I actually came up with the idea for this beanbag.  Then I went looking for one and of course found they already existed.

This beanbag gives you a secure place to attach the tripod mount of your camera to.  The beanbag is fairly hefty and has a non-skid surface on the back.  It also has a strap so you can fold it in half for extra height or for that particular angle.

It doesn't really mold into shapes very well, you can't squeeze it into a tall shape or whatever.  But it works well sitting on irregular or slippery surfaces.

I bought these dash mounts to hold my phone. The phone is larger than the pad. The pad does not slip, it is very sticky.
