I purchased three sets of these sticks at the time. The night I got them I used them for a gig. I came home with one in tacked. I am in no means a heavy hitter, although I wouldn't necessarily be a light hitter either. I was extremely disappointed that they didn't at least last a month or a few!
They are very light sticks, as many drummers would know, as they are 7A's. That and them being of poor quality are my suggestions why they were so fragile. I know I won't be buying them again. I also would be sceptical with Millennium branded products, as it isn't the first time something has broke on the first day I have got of theirs.
To sum up, you are not getting value for money. If you do get them, don't be surprised if they don't last you long.
