Fee for home audition

There are other dealers that will ship you this as a new unit and send a "demo" invoice and give you a week to 10 days to demo in your home.  If you like it then you buy it within those 10 days and keep it. If you don't like it then you ship it back.  I do know that the Grimm MU1 is in tight supply for components due to the war in Ukraine. PM me if you are interested.

So, $625 for an hour's demo at home?  Probably setup will take that long.

Rip off....  I can think of 4 dealers in close proximity that will let you demo gear at home for no fee.   I wish I knew what dealer you are talking about so I can avoid at all costs.

I once worked for a company that offered free weekend equipment loans to good customers, but charged for in-home demos. The charge was a flat fee, not some percentage of the the equipment price, and the fee helped to cover some of the cost for the time to pack up the gear and deliver it, as well as the petrol. And the consultant, who was often tied up with a single client for several hours, had to be compensated.

If you really want to hear MU1, call every single dealer here and ask for home demo. Go with a dealer who offers in-home demo with only shipping out of your pocket.
