A basic, lightweight hardware set for the jobbing player: I bought this set as I had a bunch of gigs coming up which needed a trolley and a distance load in. I've played about 8 shows now with these stands and they have been great. My only concern initially, was how playable the hi hat stand would be (with no spring adjustment) but I needn't have worried. It's Yamaha, and it just WORKS! Other players who have lifted the stands all agree how much lighter they are and a couple have bought sets themselves after checking out mine. I hope now that Yamaha follow up with a set of generic floor tom legs; stool base, and even a BD pedal - why not?! :-) I only gave 4*'s for the stability, as they are a teeny bit wobbly, bot only compared to other steel stands, and I honestly can't see these getting knocked over.
UPDATE 24/6/23: Everything still working amazingly well over 50+ gigs and 200 practice sessions per year. Nothing has ever fallen over! Highly rated!
