Very satisfied: used for work (like an "improved metronome"). It had to be very simple (0 time lost programming/configuring, etc...), and instant use (I wasn't looking for a TR-909...) Perfect for the use. It does "fills"/breaks (it's rewarding...) and it displays the tempo, so you can note it between work sessions. I had looked at a Flamma FC12 (too limited) and the Mooer (does not display tempo -> "deal breaker"). To improve it: there should be more 3/4 styles. The volume adjustment wheel on the side is inconvenient. The "outro" function would be needed. I doubt a firmware update is possible (no interface). It's a bit expensive - but just released so not surprising. Otherwise, it's a great product, recommended.
