Whilst I agree with your sentiments,  the one thing that these devices 
do not do is test your PSU !!   What they will do well is tell you that 
the PSU is working and suppling voltage at a particular level.  But not 
under load conditions !

You could have a faulty PSU and not know it.  By placing a load on the 
PSU roughly equivalent to its rating and then making voltage checks 
will give you more assurance that things are working as they should !

There is a world of difference between a classroom and a working 
environment where repairs are carried out !
