The Gaui 365 is a 3 axis flybarless system. It uses older technology sensors but is I think it is the lowest priced flybarless stabilizer system. It does have drift and vibration issues compared to the more advanced sensors. The tail performance is not in the same league as the better tail gyros. It depends on what you want as always. If you are a mild flyer and just want to get exposed to flybarless this is the lowest upfront cost way to do so using a stabilizer. If your are more aggressive do aerobatics or 3D you should probably go for one of the more advanced systems like the Mikado, SJGD FS600 etc. The SJGD is the lowest cost way to get into a advanced 3 axis flybarless stabilization unit. But you will be happy with SJGD, Mikado or Axiom as well as some of the other more expensive units such as Gyrobot. Look for help on first time set up on any of the units.
