I use them for 1 month in succession to my msp250, they are very good lyres. I tried a few models but nothing to do with the ones. Minimum: a power supply cable molded ...... not terrible at all, or a base CE powercon would have found his place. But not heavy enough for anything. A very good light, net, Internal menu very well, many adjustment possibilities, chocking ....... very fast, quiet, very good product brief advice.
