For Pressurised portafilters only - ie. the Delonghi range. Why? Because its design for it!
Positive Product Points
Its cheap - really cheap - but not in a quality or looks way - its stylish and will go well with your delonghi espresso maker. You wont find anything other than blade grinders in this category
Negative Product Points
Out of the factory, wont be ideal for espresso makers without a pressurised portafilter. You can modify the switch to do this though Maybe prone to failure due to pressure vs construction - keep a receipt handy.
Don’t forget (and the reason most people misunderstand this Burr grinder) – this is made for a PRESSURISED Porta-filter, of which many of you wont be running. Many people buy this item assuming it will suffice for their older/classic espresso maker and become disappointed the end result is not ground fine enough – there is a reason for this. A) Pressurised portafilters do not rely on the fine-ness of the ground to build up the pressure, b)The reliability of the unit is increased the less fine the ground. Now, you’re asking what IS a pressurised portafilter (I thought all espresso was pressurised) and you’d be right however, in the cheaper espresso makers, you have two differences. A) there is no boiler as the water is forced at 15bar through a tight hot S bend, b) the Portafilter has a valve which causes the build up of pressure NOT the beans themselves. This means there is less reliance on the end user to go spend $200+ on a grinder that takes up most of your kitchen. This basically means, common man (or woman) can enjoy a high pressure espresso, ground freshly that morning, that tastes great (even with a great Crème!) all for under $300. Genius design. If you DO want to use this device for youre espresso that relies on a finer grind, then you can modify either or the switch or the grinder washer which actually does the job. However, asI have a pressurised portafilter, this does the job for 10x less than I needed to spend.
