Could use an extra 1/2 click in the espresso grind region
Actually I've used the MDF about three months but that was not on the list of choices. I paid $199 from Whole Latte Love to use it with my Classic Gaggia.. It was a virtual godsend after 3 1/2 months with a Gaggia MM. The MM was noisy, messy and inconsistent when used with the Classic. The MDF is not so noisy, virtually mess free and gives me 20-30 second pours for 2 oz most of the time. Even when the pouring is too fast or too slow, it doesn't produce the wild swings the MM gave me. My crema is also more plentiful. It made a frustrating process into a fun process.
I do like the doser because it greatly reduces the mess and I use it exclusively for espresso. No drip or french press for me. I do not use it to measure. I premeasure the beans for one double shot and just grind all of it. And then I keep pulling the doser until it is all dosed.
It needs non-skid feet. Tends to slide around on the counter. Gotta fabricate some.
I'm probably just a clutz but for me an extra half-click in the espresso grind range would help. In my case the setting of 5 pours too slowly most of the time (up to 40 seconds), even with a relatively light tamp (about 10 lbs). At 6 I need to tamp very hard (about 70 lbs) to get the ideal pour. So I cannot achieve a good pour with a 30 lb tamp. But that is a minor quibble since I can get great pours at 70 lbs, using my heavy duty aluminum tamper from Espresso Supply.
