Excellent service and great products, I work for a major sporting goods company and have been recommending you to all my coworkers, thanks!
I use stuck this to be back of my preferred phone case to create a very low profile assembly. I use it to mount the phone to a number of receptacles on bikes, car dashes ( no stalk or cup ), even workbench. Very handy system.
This product is wonderful in every way. The ease of use is better than any other mount I have had. I ride a hybrid commuter bike and have experienced no movement on roads or trails. I am a user of this product for life.
I dont have a cycling computer so I use my iPhone Xs Max along with an Apple external battery pack. The combined weight of the phone, battery pack and universal interface is 338 grams. All this is mounted on a SP Connect Handlebar Mount connected to a Cannondale SystemSix. I have been using this set up since May 2020 and the universal interface is still going strong. The systemsix does not have any, or very little, shock absorption and the universal interface has my total confidence. It has not come loose or failed at all. I was worried that it would not adhere to the apple external battery pack, but as I already said there are absolutely no problems. Now that being said I do want to mention that I did very lightly wipe down the back of the battery pack with Acetone to make sure the surface was clean before applying the universal interface.
Works EXCELLENT for Motorcycles. I stuck this to the back of my phone case over a year ago. I have never had an issue. It connects to my SP ball mount which is connected to a RAM mount on my handlebar.
