I have a RSX and used it 4 times now, each time playing for a couple of hours. Shooting some 4000 balls am guessing.
It is very reliable and as fast as you probably want. I am using a HALO loader and HPA tank. Have not had a single break, and only once experienced that it did not cock properly.
I am a beginner at paintball and this is my first marker, so don't have much to compare with, but it is easy enough for me and so far very reliable. Even when using the ramping modes.
A couple of issues though. The feedneck(?) is too wide for my HALO loader, so I had to put tape around the HALO neck to make it stay attached to the marker and prevent it from falling off. The difference is quite big, the loader does not fit at all unless you roll a few rounds of tape around it.
Second issue, the ballstoppers fall out. I have lost three already and have only one left (if you don't know, there should be one pair of ballstoppers inside the "chamber" to stop the balls when coming down from the loader). The marker still works now with only one left, I have ordered new, but find it annoying that they would fall out so easily. Will try to glue them I think.
Finally, the balls seem to drift to the right at the end of their trajectory if you shoot at long distances. This is quite consistent so you can still aim somewhat by adjusting to the left, but it puzzles me. Have a friend with an RSX and he has the same issues as I have.
Been wondering what causes the right drift, the only thing not symmetric are the small air holes at the end of the barrel, wonder if that is what makes the balls drift.
Sorry if I used some wrong words, I am used to real guns and not quite into the paintball lingo yet.
Conclusion:
I assume seasoned players may have higher needs, but for a starter and semi dedicated player this seems to be very good value for money with the tadao board making it a very fast and reliable gun.
I am rating it 9 and not higher simply because I know there are guns out there costing more than three times as much as this, so there must be room for improvement. But if you factor in the cost I guess this is good 9.
