The K&M 17525 guitar stand has been designed to be extremely quick and easy to pack up or setup and works well. The guitars remain safely in place and there is a decent sized plastic barrier between guitars.
I have purchased and installed the castor set (K&M Wheel Set for Guardian) that go with this model to make cleaning around the rack much safer and easier. The guitar rack rolls very smoothly (on a hardwood floor and stage, I haven’t tried it on carpet…) even when full of guitars and there is no fear of any guitars falling out. Each wheel has an independent locking system to assure the rack will not move unexpectedly.
Because of the tight space of this product, you have to be very careful when placing and removing your guitars from the rack. Even though there is a good plastic barrier between the guitars, it is still very easy to knock one against the other. You could go with their other model K&M 17515 that can hold both an acoustic or an electric in each slot, but this unit will ultimately have a bigger footprint and will not be as sleek and compact.
Since I have many electric guitars and not so many acoustic, the K&M 17525 works great for me.
I would, with all certainty, recommend this to anyone with a need for it.
