Hi ro63rto,
If the blades are straight, aligned and firm and remain that way when you fit Bergeon blades to them (better quality steel, not what they usually have which can scratch and damage the watches), you will be ok.
I started with a similar set and fitted the good blades. Eventually I moved towards the real thing to never come back to them. In any case, they might still work for you considering quality is very aleatoric so to speak, for the brand.
Cheers,
Bob
