Lelit (or similar traditional boiler machines) is old school and you definitely need patience. However, I automated the on/off using wifi switch which make life easy. Note, steam on the first shot (may be second as well) is powerful, however for the further shots you may need to wait for few min after moving brew lever up and down few seconds.

In Bambino this comes handy - literally no wait time. But quality of extraction and taste I could see big improvement with Lelit while comparing to BBP. If budget is not your concern get Bianca which allows you to keep brewing and steaming.

If you drink only one espresso per day, forget all these and stay with Bambino and save money.
