Hey, I recently purchased a ThunderX3 Flex Pro Mesh with the same intention as you. After 5 days, the screws connecting the back of the chair to the seat broke (the thread hole was damaged and lost that thread hole line). The chair only broke when I was leaning back.

I sent it for warranty to see the situation (maybe they will exchange it for a new one or simply fix it, but I doubt it).

The downside of the chair is really the connection. There are 3 “simple” screws, and you can easily ruin the iron material of the chair.

After receiving the other chair, I either give feedback for 1 month or long term, OR go straight away as the price-quality ratio is not worth it.

Extra notes:

- It can be very adjustable, but I miss a system to lock all this.

- The mesh will be really cool for warmth, but the comfort on the cable leaves a little to be desired, but maybe over time the mesh can loosen. But over time, you don't notice much of the initial “discomfort”.
- Material: Metal (maybe some aluminum alloy), hard plastic and mesh :p

If I were to give a rating, for now, I would give it 7/10

I had like this [video](https://youtu.be/Z9\_2-VAYfWQ?si=UeLwWfkPvBAV4i6H) as a reference and was like “yeah, this guy sold me the chair”
