I am a hard-hitting drummer and before I had this product, I find myself buying new sticks often. I was in a constant search for "the one".
The first time I had my hands on it, it felt sturdy and considerably heavier than the other sticks. it took me time to get used to the weight but after only a couple of weeks, it automatically became my go-to stick.
I've used this for a while and it is still very much alive and kicking. The balance is very good that you can easily switch a right stick with a left stick and won't notice a difference.
Take note that this is heavier than other sticks so if you're not used to it, you might get tired more easily.
