I've prolly had mine 10-15 years. And, just used it to change the clutch/brake fluid on my 2001 Bandit (prolly first time for it). I've used it on all my vehicles. TIP: remove the brake bleeder bolts and wrap teflon tape around the threads. Air gets sucked in past them otherwise. Afterward, the fluid is almost a continuous column, instead of all the bubbles. And don't let the fluid get into the pump (keep an eye on the spent fluid container!). It can ruin the check valves. But they are rebuildable with the rebuild kits. (Don't ask).
