Question: How long does it take for the adhesive to work
Document: If you have a Contour cam this is a good addition to your camera bag. You'll want it to add more ready attach points than come with the camera kit. The self-adhesive is pretty good, you stick it and it stays although I expect the sticky might deteriorate over time. I don't know for sure, I haven't owned one long enough but I get that sense. You can rotate the mount across 360 degrees, locking it in place with a little button. This isn't the mount you want for a helmet, unless you're mounting it on a VERY flat spot.
One of these mounts will very likely out live your camera - so $20 is not so bad. With additional adhesive pads, you can reuse and re-position the mount many times.The adhesive mounting pad holds this mount very firmly. As long as you ensure the surface is clean and dry before application, there is no reason not to consider this mount permanent. There is also a little bit of flexibility... not much... but a little. So if the surface you wish to mount to is not perfectly flat, there is a good chance you can still use this mount successfully.The mount itself is one of my favorites because it is very flat, and allows you to reposition the camera one tooth at a time.
I use this as a dash mount for my ContourROAM. It sticks to an old cell phone suction cup mount. I have been using it like that for a long time. Right now its winter and normally in the single digits in the morning. So far it sticks well in cold weather. There are cheaper ways to mount a contour but the ability to rotate the mount is why im buying a second one of these.
I like the mount but I'm not really big on the adhesive mounts. I like the ones with straps that I can easily remove. This works well on the dash of the car or somewhere else where you don't need to remove it.
this rotating mount fit my helmet very nicely. The adhesive materialthat comes with the mount is extremely effective. Be sure you getit in the right spot before you actually stick it down, because it won't moveeasily.It does come with a second sticky pad if you happen to get it in thewrong spot.
Fortunately, the adhesive came apart in my hands. I never had a chance to use it on the road as it immediately fell apart after placing my camera on it.The adhesive stayed on the helmet. It was the connector that came apart from the adhesive - a manufacturer's defect.I will NOT trust my ContourROAM to this piece of junk.
it rotates a little too easy for helmet usage on a dirt bike in my opinion. The camera can end up aimed at the sky if you hit a small branch on some single track and you might not notice it until you go to turn the camera on/off. Otherwise it works great. The camera isn't going to slip off the mount and the adhesive for the mount is extremely strong.
It has a loop to secure the safety line, so I will not lose it if it does. The mount comes with two adhesive pads. They seem to be 3M extreme mounting tape or similar. They are very strong, yet not too difficult to remove without damage. The surface I mounted it to is slightly curved, but the mount bends slightly, so it is secure. One other gripe is the price. It seems a bit expensive for a small piece of plastic that isn't built to the tightest tolerances.
I have 4 of these for my camera. One on the side of my bike, one on the front fender, one on the tail and one on my helmet so I can change where I mount my camera.Adhesive pad is great, mount holds the camera secure and have never had an issue with the rotating part slipping or moving unless I wanted to change it.The shape didnt fit my helmet all that great but it still works well enough and hey what can you say, every helmet out there is different so it might fit perfectly on someone elses.
The first generation of this mount suffered from its fair share of problems, and this new mount addresses all of them:1) The old base was perfectly flat, which, okay, is implied in the description. But I'm guessing the vast majority of these end up on (slightly convex) snow and skate helmets. The little wings make the base slightly concave, perfect for getting as much of the adhesive pad on the surface as possible. I'd estimate 70% of the original mount pad ended up sticking to my Smith Holt helmet; the new one probably has 95% contact.
Answer: Immediately.  But as I wear it in my flight helmet hanging out the side if a helicopter, I let it sit for 24hrs.
