This price is still very good,. it really should not be compared with 354m, but it still looks very similar, all are matte materials. 354m is more delicate and smoother. The sense of magnetic force is not a level. The built-in made me doubt it once, but after turning it carefully, I can still feel the magnetic force! how to say! The price is only one tenth of 354m! It derseve the price!
