I have a CT MIDI, and like it because I have limited storage space in my SUV, and most of my projects in client's homes don't require much vacuum clean up. The problem is that it is a pain to get both the hose and power cord into the top of the MIDI.
So I bought a SYS-MFT, and cut a notch in the side of the box to accommodate the cord with lid closed. Now I can quickly store the hose where is was designed to go, and flop the cord into the MFT box and depart the job. I can easily carry the MIDI and MFT together, have a stable work bench on the job site, and have a place to store blades, commonly used vac implements, etc.
