I have.
I have two that are identical, the ones without the blade-exchanger or the corkscrew. I have tried them in my pocket for several days at a time, but have always switched back to a SAK. Here's why IMO: they suffer from a fairly poor "pocket feel", being not only chunkier than a fairly typical 4-layer SAK (take a Deluxe Tinker for comparison), but the edges and corners on the Multi-Lites are much more squared off. It's just a matter of a few millimeters, but it makes a big difference in comfort.The other thing about the Muti-Lite that renders it less quick to deploy, is the plastic cover. To use any of the tools within, you have to release and open the cover fully, dig around for the right tool (and the nail nicks are not very well thought out/integrated), open the tool fully, then close the lid fully. Repeat the operation whenever putting the Multi-Lite back in a pocket. Compare this to a SAK: pick your blade, open it and use it. To put the knife away just snap the blade closed again. That's a huge difference in usability in my book.The plastic lid itself adds several mm of girth to the tool, without adding too much functionality. I believe it could have been designed better too. Put the flashlight portion at the opposite end of the lid where there is more space available as several tools don't run full length. They could have done away with the secret drawer too, all I ever use mine for is to hold a toothpick, and that could easily be inlet into the lid, Victorinox style. The end result could easily be a lid that closes flush with the main body, not ride about 4mm proud of it. But this was all never to pass. Too bad, as the tool is remarkably sturdily made, and absorbs wear and tear admirably with it's satin-finished stainless body and robust tool-set. Everything locks securely too!!
