I'm just getting into seriously drumming and am on a budget.
Around the rehearsal room of the band I'm in are a lot of people living, so we need to keep it at a moderate volume most of the time. The brushes feel very sturdy. The handles are metal, and the nylon brushes go in and out smoothly. They're a tad uneven which makes it a bit harder for the super subtle stuff, but nothing I can't work with.
They're not perfect, but for the ease of ordering, paying, receiving and the small price I give it 5 stars.
