I purchased at PL532 to mount E21s to my DL650 VStrom. I am, at best a mediocre mechanic.
It took about 2 hours to completely install the rack on my 2011 DL650. There was some fiddling involved - the left side rack did not line up with the rear left side OEM rack screw hole, but I was able to coax the whole thing into place without too much trouble. Because the PL532 mounts under the OEM rack, I was also able to mount my existing JC Whitney topcase in it's original location, which was an unexpected surprise.
All in all, this is a great rack and a cost effective entry in the Givi "family" of cases.

I installed the Givi E21s on my WeeStrom (DL650) using an (also purchased from RevZilla) PL532 rack. The ordering and fullfillment process from RevZilla, was, of course, flawless.
I am, at best, a mediocre mechanic.
After bolting up the rack with the usual amount of fiddling that comes with aftermarket luggage/bars/handguard/etc., the cases went on nicely - I was even able to get my JC Whitney top case to re-attach and be fully functional.
I purchased these cases primarily for space on my commute - with a laptop in the topcase, there was only a small amount of room left for my lunchbox/etc. and I prefer to not use a tank bag. The cases are spacious (enough) for lunch, extra clothes, an extra visor, tools and a bunch of other stuff. They also look good (black cases/black bike), and, perhaps most importantly, the come in just a hair under 36 inches in width, or about the same width as the OEM bars - this is important as I didn't want any extra width while lane sharing. So far the cases have done well, and fit nicely in between the cars on my commute.
One thing to note - the cases did make the bike handle slightly different - it rides a bit lower, but I'm sure I can work around this by adjusting preload. The cases actually lower the center of gravity, so, after some time getting used to the cases, I think the bike actually handles better at parking lot speeds.
With all this in mind, I'm really happy with the E21's
