ULF have a wide espresso range in the Wug since it has a fixed carrier. I've choked shots on accident a number of times and with most coffees am pulling traditional pressures and ratios 100 micron from chirp. Turbos are in the high 100s to low 200 range

Of course any machine will need periodic preventive maintenance, but constant o-ring failure, damaged electronics, rusted components shouldn't be considered typical preventive maintenance fixes. Temp stable? Lots on the market... Pre-infusion is like flow control as in way overrated and more of a training wheel approach... Under $2,000? Lots of machines just as capable, much better built and will

Opinions certainly vary... I know exactly what equipment will get the job done for me and will do so day after day indefinitely. This modern fad of highly specialized equipment in an effort to get nano-particle perfection is a bit much and clearly some companies simply can't figure things out

Get a good kettle that can pour very slowly if you don't have one already. I do 18/300gr V60's with the plastic V60-01 doing 50gr blooming for 30-40s and 50gr pours after that for a total time of around 3:00min. I can make perfectly consistent V60's time after time doing that. Bitter is still overextraction so grind coarser

You clearly have no experience with those grinder as what you're writing is completely wrong. I'd also expect planes worth 100 millions of dollar to not loose a door midflight or have any kind of problems even with the most strict QC on the world and it happens. And it takes months for them to be in the air

I installed the upgrade kit last weekend... hrmph, at £29 it's disappointing but ok. If I'd bought it at the RRP of £40 I'd be requesting a refund, the quality just isn't there. My reason for upgrading was the difficulty in adjusting the grind size, and I quite fancied having a dial with some sort of indicator. Unfortunately the

Show me a machine for which the MFG. doesn't recommend periodic maint. Show me a machine that the required periodic maint. costs less than $10.00 US and takes less than an hour with basic hand tools(and a hemostat). Show me a machine that is as temp. stable, has programable pre infusion, front fill, can easily be modified (for $0.00) to

To claim 'lesser coffee' is opinion and not much else. Personally don't buy into the hype over trying to obtain that last .0001% possible improvement if the equipment can't be reliable/predictable. For any grinder to carry a cost of say $3K or more it should be perfection and last indefinitely all things considered. Not be full of low volume growing

Why "Bengle"? Google tells me the word is Scots for "a heap, a considerable quantity". Is that it?

Kind of a hard response. Well look the stalling issues with the lagom 01 with no solution and I've also seen problems with Kafatek grinders. This things can happen with smaller manufacturers. If you don't want that than buy a Mazzer, Eureka or something like that and accept lesser coffee. Maybe you don't have the patience which is fine but
