если внутри у E2R3 ничего нет, почему америкосы пишут:
Make sure you pick up a 1ml syringe or the 18 guage juice injector. The needle adapter fits common syringes.
Filling is easy, Just pop off the soft tip, you will see a disk with 2 small holes. Fill your syring with juice, put on the adapter, put the little tube inside of on hole, inject .4ml to .5ml and repeat in the 2nd hole.
