This Yamaha cymbal boom very is well made, I've just ordered a second one this last weekend because they are simply that good.
What I've noticed is that unlike my Pearl or Premier boom arms,it is lighter, but very solid. I'm currently using it for an electronic splash cymbal (12") and it is very good indeed at coping with the unbalanced weight with this line of cymbal. I get less shake when I use it on either a stand or on my Gibraltar rack and it is so stable I wish I got it earlier. I had heard from other working drummers that Yamaha's hardware was good & it's definitely true.
This short boom is solid but light, and the wing nuts have a really smooth action and nice feel:you don't have to exert much pressure or over tighten to move the boom adjustment gears, unlike many other brands. I don't mind the slightly matt finish around the gear adjustment areas, but if you're picky about unifying your hardware looks it may not be to your taste?
It is such a pleasure to use and so many drummers I know swear by this hardware for constant putting up & tearing down (it takes a beating really) that it makes good sense to use the boom if you have the opportunity. However, the only negative I can find is that the boom arm does not have a knurled surface for attachments etc...
