I have not had any experience in relation to Gameig can make chairs so far. Übers Internett I have made myself a bit clever. "Why not": This chair was often recommended so I thought.
The months of the chair's expired without problems or further. All screws and an Allen wrench totaled. One can this chair without problems alone tinker together.
I have the DX Racer F tested immediately afterwards to a LAN party, in other words I am about 10 hrs. sat on this part (of course always with short breaks).
What I noticed first. Right and left are "Support" attached to the "fix" your legs sideways. For those who so love to sit astride a chair, this is already an enormous change and the beginning also uncomfortable. (That's why it's also the 2 star deduction)
In my opinion, you should adjust the night side supports or can move.
Over time, however, it is not unpleasant but just unfamiliar.
The backrest as well as the armrests are super. Even the pillow for the neck makes sitting very comfortable.
In large and whole, I am satisfied. If you get used to the "leg supports" the chair is super.
