They are an abomination for the amateur, too, who merely wants to get
inside 
the harp to tune or change a reed or fix a gap or two or clean the
innards.  
I pay sixty quid for a double-sided Echo harp that will inevitably need

opening up fairly soon after acquisition and at frequent intervals
after 
that for this kind of maintenance and cleaning.  The cover ends distort
upon 
removal and the nail-holes are then too big to hold the covers back on

securely.  The advice from Hohner is to snap off a piece of toothpick
in the 
hole.  Ha ha!   Getting the plates off without distorting them is a 
nightmare, and same problem with tightness of the nails when you put
them 
back on.   This kind of design on a cheapie throwaway may be justified,
but 
on a serious harmonica it's just a joke.   Let's face it, the harps
make it 
as difficult as possible to take apart and put back together again. 
It's 
not good enough and it's about time Hohner came into the modern era!
