As a drummer, i have a main set with a bunch of expensive cymbals, and a secondary set with cheap cymbals that i use in things like rehearsals and such.
After owning a bunch of cheap cymbals from the big brands like sabian b8, paiste pst3/5, zildjian zbt and so on, i decided to try the cheap cymbals from the Thomann brand "Millenium", and so far, it was one of the best decisions ever.
The crash is B20, unlike the cymbals at this price range that are either brass or if you're lucky enough, b8. B20 is the material used in high end cymbals, keep that in mind.
The crash itself is loud and has a decent sustain. The finish is good enough for this price range and overall it's in my opinion, much better than the low end cymbals from the big brands.
So you can compare, this costs the "same" as the paiste 101 16" crash, and as someone who played 101 before, if i had to choose between this and the 101, i would pick this crash without looking back.
Pros: really cheap, B20, decent finish, durable (thick cymbal)
Cons: sounds like a rock/metal crash and i prefer thinner sounding cymbals (not a con actually, just my personal preference)
