The BB005 is a pretty good grinder. It's my first so I cant benchmark it to anything else.
The stepless settings are done using a small knob, which makes it possible to make very very very minute adjustments. Making changes for a particular bean does not stray much, so honestly, knowing my grinder, a turn up or down makes about a 1 second increase or decrease in extraction time.
However, to get from one grind to another, it's a pain. Which is why I'm considering to get a Forte, however, I am on the fence now if it is a substantial upgrade or should I go for a more sturdy grinder like the Mazzer Mini with SJ Burrs.
The BB005 I feel, though built with stainless steel, is lightweight, but reliable nonetheless.
The burrs do heat up a tad if I'm pulling 10 continuous shots. Hence, I'm not too sure how much the Forte would.
Finally, my biggest qualm of the machine, the ease of cleaning. Without any guide, the first time i took it apart, it took me about 30 mins to figure out without breaking anything. Now. about 15 minutes for the whole process. I dont have any Grindz, so this was my only option.
Perfect as an espresso only grinder, but I'm looking for a sturdier, easy to clean and adjust grinder.
