Highly recommended. 10amp unit also available.

Had a look as I want one too. It doesn't give any clue whether the adjustable current limit shows what it's set to or whether it's adjusted blind.

I therefore expect it's the latter.

By shorting the output out and then adjusting it? Is that what you
mean by 'blind' or did you mean more 'on the fly'?

Also beware the 0.2v ripple spec!

What would that affect, ITRW and is it only likely (to be that high a
value) to be at full load?

Also zero info on meter accuracy.

It's a 50 quid PSU. ;-)

Quite. Even rock bottom £2 multimeters have specs. No specs makes the readings fairly meaningless.
