Good quality plastics and the proverbial wooly jumper stickiness is effective.I have one of these on the leading edge of my Landrover bonnet holding a GoPro 10. No issues over all terrains and tested upto 50mph on tarred roads. Been through extremes of weathers and washes, including power washes, and it remains stuck fast with no signs of falling off. Of course it remains to be seen if I will get this off should I need it removed in future.....but for now it is doing a remarkable job.

Happy with it. Been using it to fix a GoPro 7 on a RC. After a few rides on a Xmaxx 😅 I think it’s doing a good job even after same front hits in a couple of trees . So yes, pretty good quality

I have only used the flat mounts on car windscreens, but have had absolutely no problems with them.I've no reason to suspect that there would be a problem with the curved (helmet) mounts but have not tested them.

Solid Adhisive really strong bond

The adhesive is good and forms a surprisingly good bond with the couple of things I've stuck them too, and the mount is well made and holds what ever you attach effectively.

Really like this as have a number of Gopro's to set up in different locations - easy to use and cheap as chips

Used with akaso action cam for helmet mount

These are brilliant for my crash helmet, as you get curved and straight ones,they are as good as gopro ones and are very sturdy, why pay gopro prices.
