Your general opinion of this product.
Wuhan's quality control is notoriously uneven. My 18" china bears this out a bit. The hole for mounting on a stand is off-center, and I've never seen that before, even in other cut-rate cymbals. I've heard that purchasing Wuhan's "sound unheard" is a crap shoot - some sound great, some don't, so you roll the dice when you order.
The small splash sounds good, especially for the money. The 18" china is The King Of Trash. I don't yet love the sound, but it's clearly in the "dark, trashy" category that you sign up for when you go shopping for a china. I may drill some rivets into it; I may practice on it often and hope that it will temper over time; I may swap it out for a more conventional crash and swap it in for certain gigs or recordings. The only reason this is a 3-star review is because the cymbal pack is so affordable. At a higher price, the gamble wouldn't be worth it. Be warned - and have some fun.
