Following this thread, I received yesterday:

Which for less than £15 ain't bad.

Not quite sure how to read:

"After testing, every 3 batteries can be used for 30 days, which is
very Durable and safe."

I hope that doesn't mean replacing the batteries every 30 days when
only in "standby". 30 days "on", even in 20 second bursts, seems
rather long (720 hours) from 3 alkaline x AAA's.
