I became a dealer back in January, they are very lightweight, easy to transport, and they have a mic stand mount included, but you need to purchase their size adapter.
The points I don't like was, each arm and each leg has to be detached before it can be put into its carrying bag, ( which is included ) so set up and break down time is longer than a K&M spyder .
The arms are a set size, so the deeper keyboards tend to hang off on the tower series. the Piano series are very nice, less portable.
The price is good, almost half of a K&M Spyder
