It came without double-sided tape, I put the tape I had at home to stick it to the case and it keeps coming off

It doesn't stay on a car magnetic mount. On the first pothole, the phone falls off. It might be suitable for smaller/lighter devices than the s24+.

I clearly got it for the ring on the Fold 5, because you can't manage the phone otherwise with one hand. Very good and sturdy for what it is. It also keeps the phone stable as a support in case you want to watch a movie, but it doesn't work if you want to use the phone as a tablet. It falls back. But I don't think that's the main use for which someone would buy it.
I have no opinion on the magnet because I have another type of mount in the car.
For its price, it's excellent and durable. Compared to others I had bought in the past for about the same money, this one is perfect!
The only negative is that the adhesive came off after 2 months. I put on another quality double-sided tape and now it's even better.

Quality construction, tight ring, and works perfectly on the company's corresponding magnetic base. As for the lifespan, if it lasts 6 months it will be fine. Anyway, it is very cheap

It has triple use:
1. as a ring to prevent slipping from the hand,
2. it magnetizes to a car base,
3. as a stand to keep the phone upright.
It is a fairly good construction. With a lot of use and enough wear and tear, the ring can break from the base. The disadvantages are that it adds considerable thickness to the phone and that you cannot place the phone with the back on the table

I have had it for about 8 months. I bought two to put them in the two cases I had bought for my phone. It is reliable, it has never come off, and it stays very well on the sides. The only negative thing is that it has slightly faded. Other than that, I am satisfied!

The only issue someone will face is that it does not hold the phone well in the car. It delivers on everything else it promises.

It is a quality product and definitely value for money.
In my case, I had to use the spare adhesive provided because it kept coming off during my first application. The case of my phone that I applied it on probably plays a role as it has grooves.
I would suggest that if the case you are putting it on is not completely flat, leave it for a while and press it down to make sure it sticks well.
After applying it with the spare adhesive, I have no issues, it seems to have stuck well.

I was looking for something powerful and stable, and this product is exactly that. It's better to put it in your case, as it holds better that way. It can also secure your phone in any position you want and watch videos. It is also comfortable in the hand. The color is very nice and elegant.
