The base is plastic while it looks like aluminum. Where it holds, that is, on the steering wheel. After a while, it broke while I was moving and the phone fell down.

Use on V-strom mounted in the center of the handlebar. It requires special attention when tightening it on the handlebar so that it does not loosen and the screw comes out, resulting in it coming off during vibration. It should have a notch there to secure it when tightening. However, it never came off its position for me. The point where it holds on to the phone is very secure and keeps it in place without any movement, whether you have a case or not. Be careful because in wallet cases where the phone widens a lot, it is not enough to hold it. Overall, with careful initial application, I believe it does the job perfectly fine.

It broke in the car seat without the phone. Imagine if I had that too. Then I put it on the steering wheel with the other base and it was shaking so much that I couldn't see the screen.

I don't know what happened to others and it broke, but I have been using it for delivery for the past 2 months every day. It is perfect, you put it on and take it off very easily, and even easier with the phone. It shakes a little when you fall into potholes, but don't be scared, as I said for the past 2 months, nothing has happened to it!

Terrible! It couldn't handle the vibrations and broke before a month passed! Thankfully, I didn't have my phone on it!!! It's ideal for a bicycle! But for a motorcycle, not even close!!!!!!!!!

Only for bicycles. In the two days, the plastic mirror base left us with times of vibrations on the scooter. I think it doesn't work.

The point that holds the phone is excellent. One of the most sturdy and high-quality constructions I have seen, even in positions with millimeter precision and rock-solid stability. Tested with 4 different mobiles, they all fit. The part that tightens on the handlebar or on the handlebar itself is the worst thing that has passed through my hands in the last 20 years. It is not even suitable for a bicycle moving at 20 km/h, let alone a motorcycle with vibrations. It opens easily and the butterfly screw does not secure it effectively anywhere, resulting in it coming off its position with every vibration. Personally, I modified it by grinding and adding a wheel roller at the tightening point, and it became sturdy and secure there, but here we are evaluating how it comes from the factory. At best, it is mediocre, and if it didn't have such a sturdy grip on the phone, I wouldn't have bothered to modify it.

The worst thing about it is the poor construction quality, after the first installation the rotation ball broke, resulting in the device not sitting in the correct position.

From the first application, the wheel that holds the mobile phone fell off. I also tried to use the support base for the mirror and the base broke. Bad choice, I do not recommend it. 12 euros wasted.

I use the case on my bike, on rough terrain, it shakes quite a bit but the phone remains stable. The screw that tightens the case is very user-friendly, it locks the phone very well and you can remove it without any effort. For its price, it is a very good purchase (and a very nice base). I haven't put it on the motorcycle yet, but it seems that the base they give you looks very sturdy and reliable.

Although I have driven with it only a few times, it is very good. It attaches easily with the option to mount it on the mirror screw, it is quite sturdy and does not make me afraid of my phone falling, etc., as it closes very well. Value for money.

If anything changes, I will update

Very good quality construction and stable enough on the motorcycle handlebar, I would like the way of stabilizing the mobile phone to be a little easier

The part that holds the phone is of very good quality. My heavy phone (XIAOMI redmi note 8 pro with a silicone case) fits comfortably, rotates 360 degrees, and remains stable at any angle and tilt. The rest (handlebar mount and arm for mirror placement) is of average plastic quality. The clamp that holds the mount on the handlebar (while holding it very securely) can be easily released with a finger movement, no matter how tight it is (motorcycle handlebar). This worries me about what will happen on a ride with many vibrations. The arm for mirror placement seems to be durable without having tested it yet. However, it is 0.5 cm thick, which may be bothersome in terms of height difference between the mirrors. Except for the part that holds the phone, the rest of the mount seems to be inferior compared to a Chinese one I had for 2 euros.
