Machine size - This grinder has a small footprint, which comes handy if there isn't a lot of space on the countertop.
Build - It's made mostly from plastic, with a small brushed metal plate around the button, which is a fingerprint attractor. The build is solid and it looks sturdy enough to last a good few years
Grind size - I'm mostly using it for espresso grind - it works well with standard 58mm unpressurised portafilter on Gaggia Classic. According to the grind size markings, the Espresso range is on setting 1 to 10, but there are additional 10 grind settings on the burr, which can be taken out and adjusted manually, though it's a little finicky to do. I also found that the half-steps can be used for grind settings. Overall - it doesn't look as fancy as Baratza Sette 270, but it will get the job done well. It's probably one of the best within this price range.
Grind experience - It comes with two portafilter holders for 58mm and 54(?)mm, and it should work well with most of the portafilter sizes. The holder can be removed completely so you can grind directly to the pour-over filter, or similar. The hopper can hold about 340g of coffee beans, but I'm using it as a single dose grinder with pre-weighted dose, though it does have some bean retention. When connected to the mains it tends to softly buzz, so I disconnect it at the socket when not in use.
Overall - a good starter machine at a great price point. Would definitely recommend it!
