Pacemaker

No not for geriatrics.....

I kept getting told I really needed to play along with a metronome, but I hated the annoying beep sound that they made, and then managed to conveniently loose it..

I kept seeing the "pacemaker" by sonic ventures advertised, and this makes a drum noise!

So much more fun to play along too 

I much prefer it to the normal metronome, and its got all the usual functionality you would expect,  the customer service was really good too, as the the first one get lost in the postal system for a couple of weeks, and I got sent another without any problem - ironically they both arrived on the same day!
