It took me a while to figure out where to put it (no, I didn't clamp it to the back seat armrest in my Subaru). It has much nicer clamps than my old Royal, so I wasn't worried about marring the surface of a good table; but most of the tables in the house have either a very shallow lip extending over a vertical panel, or a routed edge. And of course there has to be somewhere nearby to mount a swift. The kitchen island countertop worked great, but my family assured me that I couldn't leave it set up there.
Unfortunately, my swift doesn't work nearly as well. The screw that holds the clamp below the umbrella to the vertical post is wooden, including the screw threads, and some of the threads broke off. So it doesn't hold very well, and the umbrella has a nasty tendency to collapse mid-winding if I encounter a resistant spot. And of course, once a skein falls off the first time, it tends to have a lot of resistant spots.
By the way, speaking of using the right tool for the job: if you need to give your long-haired cat a lion cut, don't use your husband's beard trimmer. Just sayin.'
