It's an ISAF years I AIS and is not to say there is no better on the market either at the metronome-type credit card or mechanical one is perfect, easy to grip, he all necessary functions, a headphone jack, a system to find the tempo, just short of good.
In addition it is solid trs (eh leader who steals my metronome bin ...).
I would put 9 because when I was a lil but really any small defect: ca Beach beat is a bit too short from 40 to 208 if he could go up to 250 this would be good.
30 For the price there is no better.
