There are two types of mounting stays, and two fixing spacers are included. Although I was a bit nervous to install it just at a good position, there is no sound or vibration after installation. There is also rubber cushion at the part that inserts the smartphone, this is also firmly fixed, easy to remove. How many points on this product is that the letter of the instruction book is too small, it is hard to see.
It can be used vertically or horizontally, and versatility is high because it comes with multiple attachments. Because you can adjust the hold, usability is also good and the price is also attractive. I do not know how much rubber that holds a cell phone, but as rubber is deteriorated it is estimated that the body will degrade considerably so repeat.
