This is a great hack! My dash cam just came off because of this problem. Never had issue since I bought it about a year ago. I immediately went on the internet to find replacement and found one that’s compatible for $30! Insanely overpriced. Then you are to add the shipping cost plus the wait time for delivery! This not only saves me money but also time! Thank you so much!
Be careful, I tried it with hot water and it worked a bit. Then I used a hairdryer and it got better. Then I wanted to make it even straighter with the lighter and it got melted, damaging it inreversably.
I guess you'd say that! It actually works really well. I've done this to this particular suction cup at least 4 times.... It last about 4 months in hot weather... longer than that in cool weather
I've actually done it several different ways since I made that video 3 years ago. Since then, I sent the mfg of the unit an email, and they sent me one that you permanently glue to the windshield, that was about 2 yrs ago. Not a problem since then.
Jack, you are wrong. That depression under the suction cup has the role of allowing the suction cup to catch a small volume of air under it, air that will be pushed out from under the suction cup when you apply it to the place where you need it. In this way, a vacuum will be created under the suction cup, and the suction cup will be fixed there precisely because of the atmospheric pressure, which is slightly higher than the pressure under the suction cup. What you are doing there with the lighter is ... pathetic. You can improve the original product, even if it is older, with a double-adhesive silicone sheet, which will increase even more the adhesion of the suction cup on the windshield. I wanted to attach a picture but I can't.
Even easier fix. BOIL WATER. Fill a coffee mug 1/4 INCH of water. Put the suction cup in face down. (With no tension on the spring). This will flatten it out quicker and easier/cleaner. I still cleaned mine afterwards with some alcohol. Thanks for the tip. That's what made me find this other way!
