Briefly flew a Tribord R244 this morning. Build quality is not top level (e.g. a Benson or Airdynamics), but you can't expect that from a £55 kite in comparison to a kite which costs ~4x as much. Having said that, build quality is very reasonable, certainly for the money.
First flight showed the kite to track very well, and easily do basic tricks (axels, half-axels). Flight is noisy, but the leech line is easily tightened, which results in less noise and slightly higher speed.
Overall, I feel the kite is excellent value for money. Look forward to flying them as part of a team (we have 4 between us now).
