I have a large tripod and small bases, I wanted a compact one that opens up enough but also fits in a backpack. I was looking for a cheap solution, and ended up with a cheap one.
Nothing saves this product. It seems to have non-slip dots on the horizontal handle, but in reality it doesn't. Also, it seems to have a cap on the bottom of the body, but it's actually missing. Furthermore, the mobile base appears to have metal bolts for the screw, but it's actually just plain plastic. Let me speak with facts combined with the photos.
1) I have other mobile bases like this one, and I believe this one is extra to try to compensate for the quality of the tripod, but it's a disaster on its own. The first thing I did was simply pull the plastic "ear" to see how much resistance it offers as a mobile handle. As I did that, one of its caps simply came off and the cylinder emptied. It remained assembled because the other cylinder held it, and luckily I found the cap on the floor. The plastic almost completely covered the hole in the base, so in the first attempt to fit it onto the tripod screw, I had to push it to fit into its bolts. After it fit tightly, I tried to remove it and realized that the valve of the screw simply brings bolts without actually moving the screw, so you turn the valve but what you have screwed in remains trapped in the base of the tripod. I understood that the plastic valve had cracked, so I removed it and "fortunately" the screw has a somewhat hexagonal head and I managed to turn it with pliers to unscrew the mobile base. Maybe I'll put some glue on it at some point if I repair the valve.
2) Then I saw on the floor that not only the cap had come off the cylinder of the base, but also a spring that was inside to hold the mobile in its handle. I unscrewed the cap and put the spring back in, screwing the cap again. I decided to do another test with the second spring in place to see if the base holds pressure, and as soon as I released the "ear," the cap and the spring flew in front of my face. The mobile base will probably remain with only one spring and half the holding power for good.
3) The level that the tripod has only stays in place because it is slightly embedded between two plastics, it has no glue or lock. Just by holding the tripod from the top, you can push it out of its position, so it may have moved and given you an incorrect measurement or it may come out and fall somewhere, where it will break and spill its liquid.
4) The body of the tripod, which has no cap, could actually have something even better, like a hook for a weight like other tripods have. This is too light to have something to hold it steady, and the biggest weight should be the mobile that you have at the top.

Final conclusions and advice:
First, do not buy it, it will only be useful if you are the exception and it doesn't fall apart in your hands. It didn't even make it to the first use for me, and without any clumsy movement, it showed me how unreliable it is.
Second, if you are going to use it, only use it for a small action camera, not a heavy camera or a mobile phone.
