The Rocket Espresso R58 and Quick Mill QM67 are regarded as two of the best dual boiler espresso machines around. We often get questions as to which one is better as there is a pretty decent price difference. So, let's compare them.
|Specification||Rocket Espresso R58||Quick Mill QM67|
|Boiler Capacity||1.7 liters and 0.58 liters||1 liter and 0.8 liters|
|Reservoir Capacity||2.5 liters||3 liters|
|Cup Clearance||3 inches||3.5 inches|
|Rotary Pump||Yes||No, Vibratory|
|Warranty||2 years (C&P exclusive)||2 years (C&P exclusive)|
Rotary Pump - The Rocket Espresso R58 contains a rotary pump while the Quick Mill QM67 has an Ulka 52 watt vibratory pump. Edge to the Rocket Espresso R58 here. The R58 will hold heat better and is quieter.
Shot Timer - The Rocket R58 does NOT contain a shot timer where the Quick Mill QM67 does. A nice feature. Nod to the QM67 here.
Adjustable Feet - New to 2017, Rocket Espresso added height adjustable feet to the R58. The Quick Mill QM67 has no such feature.
If you're going for value and don't really care about the rotary pump and the quietness it brings, go for the Quick Mill QM67. This is an incredibly cheap, well not cheap but you know what I mean, price for a dual boiler espresso machine. Most dual boilers will be priced in the range of the Rocket R58.
Why buy a dual boiler?
Dual boiler espresso machines hold heat longer and are highly sufficient when compared to a single boiler machine. You'll be able to brew and steam at the same time with no drop in pressure as the machine contains a boiler dedicated to each brewing and steaming. Why have one when you can have two, right?
