Eezibleeds? - not a fan - too much risk of squirting fluid about for my fastidious tendencies!
First time I used my Ezibleed it worked superbly. The second time it shot brake fluid out of the reservoir; so not longer a fan. No matter how I tightened it I could not get a good seal.
Too high a pressure, maybe? They only need around 10 psi to work properly.
Maybe - ran the same 10 psi the second time as the first....maybe try again next time at 5psi.
First time I used the Eezibleed to replace cutch fluid I used the spare for air pressure.....the normal pressure pushed the clutch fluid out so fast I only just managed to re tighten the bleed nipple in time before introducing air to the master cylinder!
No issues with a seal of the reservoir to master cylinder, just check the screw cap is in good condition to create a seal and reduce the tyre pressure to 10 psi or less to slow down the flow.

is a retired nurse so I use a syringe with a long tube to remove / add fluid.... and before Aerotaff comments...
I don't wear a nurse's uniform!
