For some reason the alternatives for getting octobans are crazy prices.
These are great value. The milennium hardware on the stands is good. Although the design seems to have changed. The version i have use tom arms like pearl tom arms, two tubes with a pivot joint in the middle. Whereas they seem to be ball joint and L-rods now like tama toms. Personally i dont like ball joints, i prefer the reliability of a solid arm. However i admit they are a little limited in positions with those arms as the teeth inside the mechanicsm limits possible angles but after a while of tinkering you can get them where you want them. L-rods have their own limits but in terms of micro adjustments of angles if thats what you want then the new design will likely be better for you.
The heads that come with them sound good.
All round just good value for money, an excellent way to add more range of percussive sounds to a kit. well worth buying both sets of sizes so you have the full 4 available octobans.
One thing i would say is, it's OCTObans thomann. where are the other 4 sizes? I'd buy them in a heart beat.
